Ancillaries for Plastic Injection Moulding

Materials handling is a critical part of the injection moulding process. It involves the transportation and preparation of the raw materials, such as plastic pellets, for use in the moulding machine. The goal of materials handling is to ensure that the materials are delivered to the machine in a consistent and reliable manner, and that the material properties are maintained throughout the process.

Here are some key aspects of materials handling for injection moulding:

Material selection: The type of plastic material used for injection moulding is a critical consideration. Different materials have different flow characteristics, shrinkage rates, and melting temperatures, among other properties. Material selection should be based on the specific application requirements.

Drying: Many plastic materials are hygroscopic, meaning they absorb moisture from the air. Moisture in the plastic can cause defects in the moulded parts, so it's important to dry the material before use. Drying can be done using a desiccant dryer or a hot air dryer.

Conveying: Once the material is dry, it needs to be transported to the moulding machine. Conveying systems can use vacuum, gravity, or mechanical means to move the material.
