ABS Injection Molding PArts
ABS is the initial letters of Acrylonitrile Butadiene Styrene, it is a high strength, good toughness, easy molding of thermoplastic polymer material. Plastic ABS resin is the largest output, the most widely used polymer in injection molding industry, ABS material widely used in auto parts, household appliances, consumer products, packaging materials, industrial parts etc.
abs injection molding parts
At Goldcattle we specialize in short run/low volume custom injection molding with JIT and/or kan ban options. We can handle simple to complex molds (i.e., unscrewing molds, molds with side action features, insert molding etc.) and work with all types of engineering and commodity resins. We offer molds built in the US or overseas and prototype molds as well. We have partners that allow us to provide rapid prototype molds, stereo lithography, and selective laser sintering (SLS).
Higher demand projects in the last 12 months are: consumer products, medical, defense and irrigation. Many of our customers had been going to China for their molding needs but are now figuring out that it is more expensive to keep products in China, than to move it back to the states especially for their short run/low volume custom injection molding projects.
Goldcattle is the gold standard for plastisol dip molding and plastic injection molding products for the OEM marketplace. MDI offers a full line of protective, masking and sealing devices including caps, plugs, grips and covers as well as glass corner protectors, custom injection molding services, and busbar boots.
Goldcattle, we will mold a solution to your specific problem.
ABS injection molding Guidelines
Part design and mold design
ABS plastic parts design requires uniform wall thickness, diversity of wall thickness should be controlled within 25%, uniform wall thickness can prevent the excessive stress. Radius or additional ribs are needed on the roots of the boss and snap to improve the strength, size of the radius depends on the wall thickness, R/wall thickness should be no less than 0.3, the bigger R, the smaller stress. But you need to consider the shrinkage as well, too big Radius would cause sink mark on the opposite side of the ABS plastic part. Injection mold cooling should be designed as even as possible to avoid shrinkage problem.
Dry the ABS material before processing
Typically, heat-resistant ABS resin during storage and transportation will absorb moisture from the air, water absorption ratio are between 0.2 and 0.4%, ABS plastic material must be dried sufficiently, material moisture content must to be reduced to 0.05% before you can process it, preferably 0.02% or less, otherwise it will cause surface defects like spray, silver during injection molding process. The drying temperature usually is 80-95 ℃, drying time needs 3-4 hours.
