Improve mold running during the molding process

Make high-quality molded parts

Benefits & Capabilities of Custom Injection Molding Assembly Line

Equipped with the manual and semi-automatic assembly lines, we can help you finish secondary operations for your part like :

Ultrasonic Welding

Heat Staker

Vacumm Sealer

The secondary operation is good of shorting supply chain, reducing cost and lead time:

Custom injection molding assembly line help shorten the supply chain and decrease lead time.

One-site semi-automatic assembly line with robotics operation help to minimize labor cost.

Types of Custom Injection Molding Methods at Your Service

For injection mold, it's not only for injection plastic material. It has another way to show the material. It's not the only way to make the parts.

2K Molding

A

The product is molded by 2 different plastic materials or 2 colors which is efficient and economical. The most obvious advantage for 2K molding is cost saving. There are 2 injection steps during injection molding. That's why we call it 2K injection molding. It allows two materials with different properties, colors, or levels of hardness to be injected into the molding machine and make the molded product.
