Steps to get injection molded parts

In any injection molding project, crucial decisions must be made before the molding process begins.

The workflow often goes like this:


Select the material: Material selection is the first step when preparing for injection molding.   Product designers will typically consider specific injection molding materials when designing a new product.   And if they are unsure, making rapid prototypes is the best way to test out different material options.


Confirm the quantity: It is crucial to discuss the proposed number of molded parts to be produced at the outset.   The number of shots will determine the type of mold used: a prototype mold or a high-volume production mold.


Mold flow analysis: Injection molding mold flow analysis software provides a simulation report.   The report predicts factors like part warpage and cooling channel efficiency and ultimately helps manufacturers avoid mistakes.   In the event of a negative report, the design can be changed to improve the injection molding process.


Create the mold: Mold making is a specialist process.   These days, molds are often made via CNC machining and EDM since these processes can quickly produce highly detailed metal molds.


Create the moldings: Once the mold is ready to go, the injection molding process can begin.

The Plastic Injection Molding Process

Plastic injection molding is the process of filling a mold tool with liquid plastic resin under great pressure. The tool may comprise a single cavity or hundreds of cavities in order to make indefinite numbers of parts. Once the mold tools have been carefully designed and manufactured, the molding process consists of the following basic steps:
