Gas Assisted Mold

gas assistance injection mold

GAM (Gas Assisted Molding) is able to offer its customers a competitively priced and comprehensive range of products. In addition to this customers can also benefit from the in depth knowledge and years of experience we have in supporting Gas Assisted Molding (GAM) processes across the major market sectors. GPTMOLD is able to offer its customers an unrivalled range of technical services which include the following:

♦ Localised customer support services ♦ Design consultancy for both molds (tools) and plastic parts ♦ Mold trials for small, medium and large installations ♦ Plastic Flow Analysis using specialist Computer Aided Engineering (CAE) software ♦ Gas Flow Simulation using CAE software ♦ End to end Technical Support for the Gas Assisted Molding process

The process is used across a wide range of market sectors including automotive, TV, computing, mobile phone and domestic appliances because it gives the component designer greater freedom, the molder lower investment costs and more control over the quality of the finished part and most importantly it provides the end user significant cost savings.

Design Freedom

1. Functional integration of multiple plastic parts into a single assembly
2. Ability to combine thick and thin wall sections in the same part
3. Improved rigidity using hollow "box beam" sections

Improved Part Quality

1. Reduced warpage and distortion due to less differential shrinkage
2. Elimination of sink marks
3. Less flow marks and weld lines due to the need for fewer injection points

Reduced Manufacturing Costs

1. Lower overall weight of the finished part due to reduced wall sections
2. Shorter cycle times due to smaller wall sections and shorter cooling times
3. Less energy costs due to lower mold clamp force and plastic packing
4. Reduced assembly costs due to part integration

Lower Investment Costs

1. Smaller mold clamp force due to lower injection pressures and therefore smaller injection molding machines
2. Reduced tooling costs due lower injection pressures
3. Lower maintenance costs due to less wear and tear on the molds from lower injection pressures
