Key Process

: A short shot of plastic is injected into the mold cavity, leaving a gas channel.

1. gas filling: high-pressure nitrogen (5-32MPa) penetrates the melt to form a hollow.

2. pressure holding cooling: gas to maintain pressure, reduce deformation.

3. Exhaust Demoulding: After cooling, the gas is discharged and the product is taken out.

   The

   core advantage

   of

• saves raw materials: 10%-30%.

• shorten the cycle: 30%-50%.

• eliminate shrink marks: gas pressure holding instead of plastic pressure holding.

• reduce stress: hollow structure reduces warpage.

  Typical applications

  of

• cars: bumpers, dashboards.

• appliances: shell, handle.

• electronics: phone case, CD tray.
