The foundation of the injection molding process is the mold itself. The most common style is the straight-pull mold. This mold has two halves, a core, and a cavity. The halves of the mold, usually made from steel or aluminum, are held together in the molding press by mechanical clamps or hydraulic pressure. Molten plastic then fills the cavity to create the desired part. After the plastic cools, the halves of the mold are pulled apart.
Not every idea is a candidate for injection molding. Building a mold for an Injection Molding project can often be very expensive. Even the simplest mold can cost $10,000.
AGING − Change of a material over time, which may lead to improvement or deterioration.
ALLOY − Composite material produced by blending polymers or copolymers with other polymers or elastomers.
ANNEAL − To heat a molded plastic piece and slowly then cool it to relieve stresses.
ANTISTATIC − Agents that are added to a molding material to make it less conducting.
A-SIDE − The mold half that mounts to the fixed side of the injection molding press. Resin is injected into the part cavity via the sprue through the A-side, which is also called cavity side of the mold.
AUTOMATIC MOLD − A mold that goes through the entire molding cycle without human help.
Becoming an inventor is more complicated than most people realize. It’s not just about coming up with the product that every consumer wants to buy. You must also learn about patenting, manufacturing, packaging, promoting, and selling your product. When it comes to manufacturing and packaging, we can help. Not every idea is a candidate for …
Plastic injection molding is the process of heating raw material (plastic resin in pellet form, in our case) to its melting point, forcing the viscous material into a mold, and allowing it to cool into a hardened shape. Injection molded parts are used in virtually every product you encounter, from electronics to housewares to automotive …
Injection molding can be complex, and molders assume significant risk when quoting a project. To ensure a molder can meet the needs of a customer and to minimize the risk of making a mistake, there are often many questions asked before a quote is provided.The more information you provide – such as part or product …
