The injection molding Process

• Stage 1: A molding in the shape of the product is produced and split into two halves.
• Stage 2: At the beginning of the manufacturing process, the two halves of the mold are clamped together tightly by the molding machine.
• Stage 3: Plastic pellets are loaded into the machine via a hopper, which then travel through a heater and are melted down into molten plastic.
• Stage 4: The molten plastic is injected into the mold so that it completely fills it, before being cooled and turned into a solid form.
• Stage 5: The two clamps are separated, with the finished product then being ejected from the molding machine.

Types of injection molding

It is difficult to classify injection molding processes into broad categories because the general principle is the same across the board. However, there are specific requirements that call for certain aspects as different mould designs and heating systems, and this is where deviations occur in injection molding. These types of injection molding are briefly discussed below; however, they do not make a comprehensive list as new methods are being developed to meet the demands of new requirements.

• Thermoplastic injection molding
• Over-molding
• Insert Molding
• Cold Runner injection molding
• Hot Runner injection molding

How to Reduce Mold Cost?

injection molding can be an expensive process, but there are several ways in which you can reduce mold costs, including:

Eliminate undercuts Remove unnecessary features Use a core cavity approach Reduce cosmetic finishes Design parts that self-mate Modify and re-use existing molds Monitor DFM analysis Use a multi cavity or family type of mold Consider your part sizes
