In the machine industry, there are many people who are aware that Plastic Injection Molding is just as necessary and important as any other machining process. Plastic injection molding equipment should be purchased after considering the following factors: shot volume, tie bar distance, ejector travel, platen dimensions, and tonnage. Shot Volume An injection molding machine’s …

Designers need to gather all information before they start designing a mold. Do you have a product design that is ready to go? Having information missing or making changes to the mold after beginning can cause frustration, and it wastes valuable time. How do the tolerances look? In the first estimate of the mold cost …

How Products Are Developed A key component of product development is mold design. The relationship between product and mold design is such that both product and mold design engineers will benefit from knowledge of the design and production of plastics parts and molds. In Figure below  you will see the steps involved in the typical …

For a design to be successful, all the necessary information must be available before beginning. If this simple rule is ignored, many bad things can happen, such as poor designs, misunderstandings, poor component quality, and disputes between suppliers and end users. Experienced designers will almost certainly follow all the steps to avoid pitfalls, but even …

As a result of injection blow molding, injection molding and blow molding are combined. It is possible to use either a vertical or a horizontal plastifier to convey the thermoplastic resin from its hopper and and mix it into a homogeneous melt for injection into the heated manifold using a screw for mixing. In the …

An injection molding operation is a process by which plastic materials molten in a mold are injected, and then cooled down, in order to achieve molded products. Methods such as this are suitable for mass-producing products with complex shapes, and play a major role in the sector of plastic processing. A mold must be properly …

I’m here to tell you that injection molding is really not as hard as it sounds. It’s quite easy, actually. Once you know what you’re doing, of course. If you want injection molded products for your project, but don’t have the injection molds already made, this  should serve as a helpful injection molding guide for …

Side Cores What are the best methods for releasing severe threads or cuts? Do side cores, splits, or other methods work? In addition to the added complexity of the mold structure, adding any of these features will significantly increase the cost of the mold (and the cost of the product), not to mention the additional …

Surface Finish of Injection Molding Molded components are prevalent in nearly every industry, from highly aesthetic housings to internal components which do not require fine polishing. Individuals do not pay much attention to how the surface of these components is finished. But engineers and product designers must consider it when designing components. Surface finishes are …

In a quotation (or “quote”) to a customer, the following information should be included: Date on which the quotation was provided Details about the quoted plastic mold, including the type of machine and ancillary equipment used to make the mold. The plan should also include specifics about the mold, such as the design of the …
