Plastic Mold Company Management

Job Shop Management Software Can Really Help A Plastic Mold Company

Wouldn’t it be great if there was some kind of job shop management software that actually helped run your business? One that was designed for small to medium-sized companies in a real-world job shop environment?

Personally, I think plastic molding manufacturing and plastic injection molding must be two of the most difficult to mangage businesses anywhere. But, maybe other industries say the same thing!


You have deadlines, due dates to meet

There is so much to manage and so little time to manage it

  • Plastic Mold Company to keep track of: steel, graphite, copper, mold bases, components, special items, cutters, grinding wheels, WEDM wire, etc.
  • Quotes need to be made and tracked
  • Progress reports must be made
  • Design must be done and kept current
  • Labor costs need to be tracked
  • Labor divisions need to be analysed for future quoting
  • And on and on and on

No modern business can function very long without serious shop management. A quality job shop management software program could make life a lot easier, if it really worked as advertised. The days of “winging it” are long gone. You might get away with it here and there, but in today’s competetive environment, you need more precise control over your operation.

Looking for good plastic mold company then china plastic injection mold could be one of the most important information for your new products development,

EDM Tooling

Which EDM Tooling Sytem Is Best?

There are several very well designed and reliable EDM tooling and electrode managing systems on the market today. Each has it’s advantages over the other, but all are quite good. Time spent analyzing the various systems available is time well-spent. Your needs are unique, and you will be “married” to the one you choose for a long time.

There is no question at all regarding the benefits of using an EDM tooling system. Your quality will increase, your productivity will increase and your plastic injection mould makers will quickly see the benefits. The electrical discharge machining operators will also be very grateful that they no longer need to indicate and locate everything ‘to death’.

Time is money, and an EDM tooling system saves a lot of time.

You might need to change your shop culture


A common problem with implementing a new electrode holding system is the change in shop culture that is required. This was especially a problem in the past. One of the best ways to do this is to designate two moldmakers as the team to study and develop the idea. They will feel personally responsible and take ownership of the project, which will influence the rest of the shop.

You must make sure your moldmakers understand what you are doing and why. Change is always difficult and many moldmakers have been doing things a certain way for many years. They often see this new system as a waste of money and unnecessary.

Time spent discussing the change, and showing how and why things will improve will go a long way. Very soon, everyone will easily see the rationale behind the decision and be “on-board.” A demonstration of the repeatability is a great way to convince the skeptics.

Once your moldmakers can see the labor savings and ease of use, they will be enthusiastic. Very few people really like making electrodes the “old school” way. For one thing, it is very tedious and messy. read more about EDM tooling please go to our plastic mold manufacturing company.

Features to look for in EDM tooling



  • Repeatability. In real life can it repeat within the tolerances claimed by the manufacturer?
  • Ease of set up and use. Does it take a lot of time and labor to mount electrodes and set it up in the EDM and CNC machining center?
  • Is it cost effective? Take some time to analyze the cost savings as well as the “headache” savings. Any EDM tool holding system is expensive, but, over time, the savings can be dramatic.
  • Does the system have compatible fixtures for various sizes of electrodes? You should be able to use different size holders interchangeably.


    Not everyone uses EDM tooling!

    Sure, there will always be the odd time when you need to use a “stick” electrode, maybe even often on certain applications. But any serious mold making shop today is crazy to still be using angle blocks, vee-blocks and so on. It is so incredibly inefficient to make tedious set-ups by hand, over and over again.

    Yet, this is precisely the case in the newly emerging areas, such as China. It is quite common to get a box of stick electrodes with the plastic mold that they have just sent. They figure that their labor is so cheap that they can afford to operate this way.  Most likely, it is just a matter of time before they figure out that this is a foolish way to operate. It just makes sense to have an integrated system that is reliable and that eliminates the need to constantly be checking for alignment and location.

Injection Molding Process

The injection molding process

In the injection molding process, thermoplastic resins are melted and the melt is forced (injected) into a mold.

     In the injection molding process, thermoplastic resins are melted and the melt is forced (injected) into a mold. After this melt cools until the polymer solidifies, the parts are removed (ejected) from the mold. Injection molding permits mass production net shape manufacturing of high precision, three-dimensional of plastic parts[1]. One of the most common plastics manufacturing processes, injection molding can produce parts weighing as little as fraction of a gram or as much as 150 kg[2]. The process currently consumes 30% of polymeric resins[3] of which 90% are thermoplastics (i.e., capable of being remelted)1. Major advantages include capabilities to produce parts with: 1) virtually unlimited complexity, 2) fine details and good surface appearance, 3) controlled wall thickness and excellent dimensional stability, and 4) requiring limited or no finishing.

The five important thing in the injection molding process are the

1. Injection molding machine

2. Mold

3. Material

4 Method

5. Man (i.e., operator).

While there are many variations of each M, this discussion is limited to single-stage reciprocating screw injection machines and the flow of thermoplastic polymer melts in two-plate cold runner molds.

1. Injection Molding Machines

As illustrated in Figure 1, injection molding machines have three major components: the 1) injection unit, 2) clamping unit, and 3) controls. The injection unit plasticates (melts) and injects the polymeric material into the mold. The clamping unit supports to the mold and provides the mechanisms for opening and closing of the mold and for ejection of molded parts.Injection Mold China

Figure 1. Injection molding machine

During a thermoplastic molding cycle, the clamp of the injection molding machine closes, thereby closing the mold. Molten plastic located between the nozzle and screw in the barrel of the injection unit is forced (by the screw) into the mold. The controlled volume of melt injected into the mold typically fills the cavities to about 95 to 98% of their total volume. After injection is completed, the screw is pressured for a given period of time. In this packing stage, more melt is forced into the mold to compensate for shrinkage of the melt as it cools. The packing stage is followed by a holding stage, in which a controlled pressure is exerted on the screw for a specific length of time. Holding pressure prevents the melt from flowing back into the runners. When the gate freezes (solidifies), melt can no longer exit the cavity and the holding stage ends. While the melt cools immediately upon entering the cavity, a ¡°formal¡± cooling stage follows the holding stage. During this period, the part cools until it is capable of withstanding ejection forces. The screw also rotates to melt more plastic and build up the molten plastic shot for the next molding cycle. At the end of the cooling stage, the mold is opened and the part is ejected.

Today lots of person or companies are looking for Injection Mold China partners for their plastic molding business, this is high speed to American and Europe

The times associated with a convention,

all molding cycle are shown in Figure 2. For 2 to 3-mm thick parts, filling occurs in less than 5 s, packing requires one-third of the fill time[5], the holding time depends on the gate size, and cooling is longest part of the cycle. Thin-walled parts (i.e., wall thickness is less than 1 mm), however, filling in less than 1 s, typically have no packing or holding stage, and cool rapidly. go to our plastic molding official website to get free quote for your plastic molding project.

Injection Molding

The injection molding process affords many opportunities to enhance part functionality and reduce product cost.

The injection molding process affords many opportunities to enhance part functionality and reduce product cost. For example, the per-part mold costs associated with adding functional details to the part design are usually insignificant. Molds reproduce many features practically for free. Carefully review all aspects of your design with an eye toward optimization, including part and hardware consolidation, finishing considerations, and needed markings and logos, which are discussed in this section.

Consolidation

Within the constraints of good molding practice and plastic mold construction, look for opportunities to reduce the number of parts in an assembly through part consolidation. A single molded part can often c

ombine the functionality of two or more parts. a good plastic molding parts come from a good Plastic molding factory

Hardware

Clever part design can often eliminate or reduce the need for hardware fasteners such as screws, nuts, washers, and spacers. Molded-in hinges can replace metal ones in many applications. Molded-in cable guides perform the same function as metal ones at virtually no added cost. Reducing hardware lessens material and assembly costs, and simplifies dismantling for recycling.

Finish

Consider specifying a molded-in color instead of paint. The cost savings could more than justify any increase in material cost for a colored material with the required exposure performance. If you must paint, select a plastic that paints easily, preferably one that does not require surface etching and/or primer.

Markings and Logos

Secondary methods of adding directions, markings, and logos — including labels, decals, printing, stamping, etc. — add cost and labor. Molded-in techniques, when applied properly, produce permanent lettering and designs at a very low cost. Mixtures of gloss and texture can increase contrast for improved visibility.

Miscellaneous

Look for opportunities to add easily-molded features to simplify assembly and enhance product function such as aligning posts, nesting ribs, finger grips, guides, stops, stand-offs, hooks, clips, and access holes.

Rapid Injection Molding

Rapid injection molding & Chinese injection molding

Rapid injection molding is exactly what the name implies, but multiplied by a factor of 10! It is hard to imagine that anyone could offer a service that can guarantee a fully functioning injection mold in a day or two, but that is actually the case.

This is precisely what rapid injection molding is all about. Rapid, as in very rapid! These molds are made of high grade aluminum and can produce anywhere from a few parts to thousands.

Personally, I have worked on many aluminum molds that produce high quality parts even after several hundreds of thousands of cycles. At first I was highly skeptical, but after several years of making injection molding prototypes, It became routine.

How does rapid injection molding work?

It works by automating as much as possible in the mold making procedure. By taking the customer’s 3-D model and automating the design and manufacture of the mold, the lead times are cut down to a fraction of the conventional process.

One of the central parts of the automation process lies in the design of the plastic part. By working with knowledgeable designers, many features, such as undercuts, can be minimized or eliminated.

Some of the features that must be considered are:Chinese injection molding

  • Part draft angles and radii
  • Ejection
  • Using straight pulls whenever possible
  • Simple approaches to side actions
  • The CNC milling process
  • Part size limits

Rapid injection molding PDF papers

You can find out everything you need by reading the PDF papers on rapid injection molding. They cover every aspect of the process and are very well made. Just click on the design volume you wish to read about.

What are the advantages of rapid injection molding?

  • A way to bridge the time gap between prototype and full production. If you need a working injection mold right now, this is the answer.
  • Short run production to get your product in the marketplace immediately.
  • Gives engineers a working model to approach a full-blown design for a production tool.

What are the disadvantages of rapid injection molding?

  • The aluminum molds are low production.
  • Works best for simpler parts with minimal side action and undercuts.
  • EDMmachining is eliminated, thus some detail may be sacrificed.
  • The entire core and cavity are high-speed CNC machined, often on 5-axis CNC machines, therefore the design has limitations.

Is rapid injection molding expensive?

Surprisingly, the cost is quite reasonable, though there is always a premium to pay for extremely quick turnaround. Typically though, the cost is much less than might be expected. This is due to the highly developed automation process of this type of mold making.

Conclusion

Rapid injection molding is a niche market segment of injection mold making. It serves a highly specialized marketplace, yet is very important withing the niche. The ability to get your injection molded plastic part to market in a matter of days is very valuable to the right company.

Aslo, the ability to bridge the gap between prototype and high production is a very useful tool for custom injection molders.

What Are The Best Plastic Injection Mold Components?

Plastic Injection mold components are a very important for Plastic mold manufacturers, but often overlooked part of the plastic injection mold making process. These would include things such as: ejector pins, core pins, leader pins, leader pin bushings, pillar supports, rest buttons, interlocks, and much, much more.

Why are high quality plastic injection mold components important?

Cost- it is nearly always cheaper to purchase a custom mold base and the accompanying components. Why waste your time on the “grunt” work, when the profits are in the mold making? Of course, there are certainly exceptions, but generally, it is more profitable to purchase a standard mold base and the related components.
Consistency- Since a good supplier will guarantee close tolerances, you can focus your attention on the cores and cavities, instead of more general machining. The profit is in the cores and cavities, so why spend time making something that can be purchased cheaper and made just as well, or perhaps better? Even if it costs a bit more, it still makes good business sense most of the time.
Delivery- a good supplier will deliver just what you want, on time. Plus, you don’t have to pay for the scrapped parts he made while filling your order. This is especially true if you need more than one or two pieces.
Flexibility and innovation- companies are constantly searching for new and better ways to make components and improve their applications. Think about lifters, for example: there are numerous clever ways of making lifters, each one better than the rest! Take advantage of this collective inventiveness instead of relying on what worked 20 years ago.
Good communication- using standardized plastic injection mold components is often a selling point. Some companies have “favorite” suppliers for their hot-runner system, for example. This also can make communication easier, since the features and sizes are catalogued and common.
There is very little reason anyone would make most of the injection mold components used in their plastic mold. There is simply no way that to justify making things such as ejector pins, mold base bushings and leader pins. However, there are always special cases where it is practical to custom manufacture components. Special ejector sleeves, custom core pins, custom lifters or unique slides would certainly fall under this category.

Even in special cases, it is often well worth checking to see if a custom manufacturer can quickly make your special component. This can free your skilled mold makers to focus on the core and cavity work.

It is fairly common to waste huge amounts of hours making a mold component that you later discover could be purchased from a reputable supplier. Sometimes the cost savings are quite substantial, get to know more information about plastic injection mold components please visit our company website to know more.

Plastic Mould Development

Plastic Mould Technology

It is not surprising, on regular schedule companies as well as organizations work well with innovative mechanism typically are manufacturing mechanical products. So then, it is believed that those organizations and companies may have in-house engineering expertise panel, however, they are supposed to focus on project management platform for plastic mold development units.

In this present globalization, plastic molding and injection molding have become popular and widely used to produce necessary components with a number of complex high production volumes and geometric shapes of course. In this foregoing discussion, the advantages of mold manufactures have to be exposed after the initial product design: the expertise panel ensures the designs of the products are a good forming process, apart from that the plastic mold development is modified by specific type of design respectively. On the other hand, the plastic injection molding and injection molding ensure to prevent ill-considered haste and affect the duration. Now, you may think about the cost and other concerns, let us involve into the matter clearing the doubt; the production of these crucial moldings lessen the cost of production and shorten the cycle at the same time.

Plastic can be molded into several forms and roughened for commercial purpose. Keeping in mind this very concept,
plastic molding you can see everywhere depending on the manufacturers’ needs and demands. There are so many plastic molding processes that fit your resources and expertise as well. Injection molding, compression molding, blow molding, rotational molding and many more. According to the present demand, Injection molding has been listed at the top. Being a manufacturing process for constructing machinery and parts, in mass-production process injection molding is mainly spotted, where the similar parts are being manufactured millions of times in succession. The prime advantages you may aware of why Injection molding became known to all. Once the preliminary costs have been funded, the Injection molded manufacturing process becomes extremely shortened as per the price per unit. A variety of household appliances depend on the shape of the Plastic mould; the focus of the section primarily concerns about the shape of products and will mold the quality for sure. With the rapid development in the recent years, the general engineering of plastic industries continuously improving its strength and meticulousness. Having said that, a top-notch plastic mold development not only can often be replacing the conventional mold process, but the trend and use of industrial and plastic household products continue to rise.

Faster development, a greater level of innovative solutions, better collaboration and communication depend on current prospects of our recent culture and creativity. Mechanical and technical expertise are the burning factors to drive any industrial prospects to the next level. Throughout high-skilled engineering and proto-typing process, the plastic mold development cuts away substantial percentages despite this.

Injection molding manufacturing process typically comes from waste plastic, concerns about four zones: the runners, overflow materials, the sprue, the gate locations. “Flash” is the very condition, you may know about. High-precision CNC machining and its associated forming process liaise with the use of CAM/CAD/CAE technologies to mold design and analysis. In light of the evidence of these advanced technologies, there are a number of milling equipment used globally like EDM, CNC including the high-precision coordinate measuring instrument, high-precision grinding machines, computer design and related software. 300-1000 injection molded prototypes characteristically generated by an injection mold device in the production process. Plastic and non-plastic mold depend on a range of products and materials and the use of mold will determine the casting mold, i.e. die stamping, forging die. Prior to the great technology for finished production on a gigantic scale, 3D printing can be done in the initial process of design.
