Understanding the Process of Rubber Injection Molding

There are two types of rubber available in the market: these are the natural and synthetic rubber. Rubber has been around for more than hundreds of years now and it has already been used by most of the industrial companies in creating different kinds of materials. Since rubber has played an important role in our life, the process of creating it has been improved using the rubber injection molding.

The main function of rubber injection molding is to process rubber parts, which is being used in machines and other mechanical parts. It comes in different sizes that will fit in various components. It is usually found in press shop and other industrial companies.

The process used in rubber injection molding is not that hard because it will all depend to the machine. The process will begin by acquiring the rubber’s design using a mold that is made from a metal that has an exact size and dimension as the rubber part. This mold is being inserted in a press that is connected in a system called the rubber injection. Once the mold is already inserted to the press, appropriate pressure is being applied. The rubber will be injected to the mold using a screw or a large ram. Through the nozzles, it will be passed into the mold cavity where it is being cooled down. As the process of cooling the rubber goes, it will slowly separate from the mold, while it acquires the design of the mold.

Rubber silicone molding parts does not have any heater elements applied. The process of injection press allows the rubber to acquire the specific design of the mold, which is commonly made from stainless steel. There are two types of rubber injection molding these are the vertical and the horizontal molds. Both have their own advantages and disadvantages when it comes to its process.

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.

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

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.

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.
