Plastic Molding Machines

Over-mold plastic molding and double injection molding are two distinctly different molding methods even though both are used to combine multiple polymers into a single part. Because of this similarity, the two are often confused or misapplied by the design engineer. The more finite capabilities of these two molding methods differ as much as their required tooling, machines and often, the resulting part cost. Choosing the right method can be a critical factor usd in achieving targeted features, cost and time-to-market. Both methods can be used to create the soft-touch products popular in today’s marketplace. However, both methods can be applied to other applications where multiple polymers must be combined into a single part. Over-mold injection molding is used for parts that do not require fine detail and can absorb the higher cost of machine time and labor. 2-shot injection molding is reserved for parts requiring fine detail and low part cost.

The 2-shot injection moulding process creates the first plastic component, and the material molded round it, using a single mold and a 2-shot injection molding machine. 2-shot machines have two-barrels (one for each material) and they have the ability to rotate the mold. The machine injects the first shot material into cavities on one side of the mold, rotates the mold 180 degrees, and then injects the second shot material onto the first shot. The first and second shots occur at the same time. When the mold opens, it ejects the completed parts from the second shot cavities and it rotates the mold to position the first shot for the second shot. This is accomplished in a machine running in an automatic cycle. Because the 2-shot injection molding process is fast and highly repeatable, the shrinkage of the first shot is very consistent and two materials can be molded together with virtually no flash. 2-shot molding is the process of choice when molded-in graphics or other fine details are required. The elimination of the shrinkage variable allows 2-shot molding to produce details impossible to achieve with over-mold injection molding.

Double injection molding

As with any process, there are advantages and disadvantages associated with plastic injection molding. The advantages outweigh the disadvantages for most companies; they include being able to keep up high levels of production, being able to replicate a high tolerance level in the products being produced, and lower costs for labor as the bulk of the work is done by machine. Plastic injection molding also has the added benefit of lower scrap costs because the mold is so precisely made. However, the disadvantages can be a deal breaker for smaller companies that would like to utilize plastic injection molding as a way to produce parts. These disadvantages are, that they equipment needed is expensive, therefore, increasing operating costs. Thankfully, for these smaller companies, there are businesses that specialize in custom plastic injection molding. They will make a mock up mold to the exact specifications, run it through the complete process and present the completed piece along with an estimate to complete the job to the customer.

Thermoplastic injection molding is the most widely used of all plastic processing methods. The injection molding machine reduces pelletized raw material and colorants into a hot liquid. This “melt” is forced into a cooled mold under tremendous pressure. After the material solidifies, the mold is unclamped and a finished part is ejected. Injection molding offers the lowest piece prices available, but tooling prices are generally the highest. Thermoset injection molding is similar to thermoplastic  injection molding except that uncured thermoset resins are mixed, injected, and held in the mold until cured. As with thermoplastic molding, the price per piece can be low, but the tooling prices are generally very high.

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.

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.
