What is a Custom Molder? (5 Key Points Explained)

A custom molder, specifically in the context of injection molding, is a manufacturer that specializes in producing parts by injecting material into a custom-designed cavity in a mold.

This process is commonly used for manufacturing plastic parts.

What is a Custom Molder? (5 Key Points Explained)

1. The Creation of a Mold

The custom injection molding process starts with the creation of a mold.

The mold is designed to have a specific shape and cavity that matches the desired part.

The mold is then closed and maintained at a fixed temperature for a certain period of time.

2. Injection of Material

Once the mold is ready, the material, usually in the form of plastic pellets, is injected into the mold cavity under pressure and heat.

The material flows and fills the cavity, taking the shape of the mold.

Some excess material, known as mold flash, may flow out of special grooves in the mold.

3. Curing and Removal

After the curing time, the mold is opened, and the finished part is removed.

The part may require further processing or finishing, depending on its specific requirements.

4. Advantages of Custom Injection Molding

Custom injection molding offers several advantages.

It allows for the production of complex shapes in large quantities.

The process can achieve good dimensional tolerances and can incorporate unique geometric features.

It is a versatile and efficient method for manufacturing plastic parts.

5. Quality Control

It is important for a custom molder to accurately cut or weigh enough stock for each cavity to avoid defects such as flow lines, blisters, or unfilled parts.

Additionally, the custom molder needs to carefully manage the amount of material used to prevent excessive flash that can be difficult to remove.
