Plastic Injection Mold Fabrication Process Innovation

Technological breakthroughs in plastic injection mold fabrication processes to meet diverse needs:

1. High-gloss injection molding

Principle: Steam preheats the mold to above the resin's glass transition temperature (Tg), followed by rapid water cooling after injection to set the mold.

Advantages: Eliminates weld lines and increases surface gloss to over 90%. Suitable for mobile phone casings and automotive interiors.

2. Gas-assisted/water-assisted injection molding

Principle: After partially injecting the molten material, high-pressure nitrogen or water is used to push the melt through the mold and cool it.

Advantages: Material savings of up to 50%, eliminating sink marks on thick-walled parts. Suitable for automotive bumpers and air conditioner housings.

3. Low-pressure injection molding

Principle: Hot-melt material (such as TPU) is injected into the mold at a low pressure of 1-5 MPa to protect delicate electronic components.

Advantages: Equipment costs are 30%-50% lower, with molding cycles as fast as 10-30 seconds. Suitable for sensor packaging and medical circuit boards.
