Gas Assist
Gas assist injection molding is a low-pressure process utilizing nitrogen gas to apply uniform pressure throughout the molded plastic part.
By displacing molten plastic from thicker sections of the part toward areas in the cavity that are last to fill, nitrogen gas pressure creates channels within the part. Through the gas channels, pressure is transmitted evenly across the part, eliminating warping, sink marks and internal stress.
As a result, reductions in clamp tonnage, cycle time and part weight are realized while the strength and rigidity of the part is increased.
Gas assist allows molders the freedom to design plastic parts without restrictions and limitation inherent to conventional molding.
Water Assist
Water assisted injection molding is the newest way to mold hollow or partially hollow parts. It is similar to gas assist molding as a means to core out thick sections, but the advantage of water injection technology is direct cooling inside the part. The thermal conductivity of water is 40x greater than gas, and also has 4 times the heat capacity of gas.
The chief difference between water and gas is that water is not compressible. When injected into the melt, the leading edge of the water forms a solid boundary, or highly viscous membrane. This membrane forces molten material forward instead of the polymer forcing the water to the side.
The primary reason for this action is the higher viscosity and incompressibility of water compared with gas. This viscous front acts as a ram that cores out the part and the front also cools the melted plastic as it is pushed down the mold cavity by the water pressure.
Automation
UPM thrives on the challenges of high volume molding to produce quality parts at a mutually beneficial price. We have demonstrated expertise in implementing automation at the injection molding machines with flexible work cell automation systems.
- Monitoring with customized reports
- Report real time status on every job
- Graphically illustrate scrap and downtime
- Summarize performance by job, machine, mold and part number
- Create dozens of standard reports that use Pareto and pie charts
UPM can assist in tooling implementation and work to provide a complete automated solution for your program.
