Product Description:
GAS ASSIST MOLDS Gas Assist Molds Maker Gas Assisted Injection Moulding China Mold
Basic
concept
Plastic forming process where a plastic melt is injected into a mold and where also a gas injected for pushing the melt towards the mold internal walls where the melt is solidified.
Tool features:
1. High requirements for part surface treatment.
2. thick wall thickness product.
Part function: Handle for Suitcase
Part Size: 162X151X16mm
Tool Size: 350X550X297mm
Part material: PP
Insert steel: ORVAR SUPREME 8407 (H13 Equivalent)
Cav. QTY: 1X2
Gas Assist Molds Advantages
Less plastic material needed (material savings)
Reduced part weight (in some cases up to 40%)
Decreased cycle time
Increased part strength and rigidity
Reduced warpage and distortion
Improved part appearance (eliminates sink marks and surface blemishes)
Reinforces ribbed parts
Increased design options for complex parts, reducing multiple part assemblies, and metal to plastic conversions
Enables use of smaller plastic injection molding presses
In gas assist plastic injection molding, the pressurized gas follows the path of least resistance and displaces the plastic material in the thicker areas of the part, leaving hollow sections for reduced material use and part weight, yet not compromising part appearance or functional performance.
With gas assist molding, localized gas pressure within the mold results in better packing of the plastic which reduces warpage, shrinking, surface blemishes, sink marks and internal stress. Gas assist injection molded plastics generally make for stronger and more aesthetically pleasing parts.
Gas assist molding is used to reinforce ribbed parts and provides more design freedom for complex parts, reducing multiple part assemblies and metal to plastic conversions.
The need for less plastic material and the consistent pressurization within the mold also enable gas assist injection molded plastics to cool faster, reducing cycle times and increasing plastic injection molding machine output – saving time and cost!
In gas assist plastic injection molding, the internal pressure provided by the nitrogen gas enables lowering the outer force needed to hold part shape, so large plastic parts can be produced with less tonnage on smaller plastic injection molding machines.
Disadvantages
This molding technique is very difficult to apply for multi-cavity mold, especially if the cavity sizes are dissimilar. Clear or transparent plastic materials are an inappropriate option for this technique as cosmetic-appearance can deteriorate
Applications
Some applications benefiting from gas assist plastic injection molding include:
Appliance handles
Medical equipment housings
Interior and exterior automotive handles
Large covers and panels for office equipment
Lawn mower handles
Steering wheels
Basketball backboard frames
Long tubular shapes, such as shovel handles
Large parts with ribs and bosses
WIT Mold supply all kinds of molds, such as conventional plastic molds, precision injection molding, unscrewing molds, two shot injection molds etc., and are mainly exported to North America, Europe and other parts of the world.
