The ABS material must be fully dried to reduce the water content of the material to below 0.05%, preferably below 0.02%; otherwise, surface defects such as spray and silver streaks may occur.
Then, they should be placed on the workbench and fixed with clamps while they are still in a high-temperature state (it should still be very hot, which is crucial).
The electronics industry uses ABS plastic for a variety of products, which include cell phone cases, computer housings, and TV remote controls.
For heat-resistant ABS, reasonable holding pressure and time directly affect the internal stress in the ABS plastic parts.
The plastic components produced will have excellent mechanical properties; they are resistant to impact and abrasion, even at low temperatures. ABS plastic parts can be used in extreme environments such as hot water, steam or even in the presence of acids or alkalies without any degradation of their properties.
As the ratio increases, the internal stress gradually decreases, but the sinks of the product on the surface should also be solved.
Our process will make your process simpler; whether your ABS injection molding product is still strictly a concept or is already a work-in-progress, or you are currently working with the copy of ready ABS injection molding parts-every stage of your product lifecycle will be streamlined for you.
Due to the extremely serious molecular orientation arrangement of large-scale ABS injection parts and uneven cooling of the mold, the shrinkage of the ABS injection parts in all directions is inconsistent, which makes the thin large-plane ABS injection parts prone to deformation and distortion.
We aim to be your partner,and We are enabled to design, manufacture, and distribute the ABS injection molded products at prices that are internationally competitive and that meet the highest quality standards.
The automotive industry is the largest consumer of ABS plastic, such as dashboards, door panels, and other interior and exterior components. Most of them need ABS with FR(flame retardent)

The holding pressure increasing will make the molecular gap smaller, the range of chain segment movement smaller, the volume smaller, the density larger, the force between molecules increased, which can decrease the shrinkage and improve the internal quality of the product, but it will lead to greater internal stress.
The medical industry uses ABS plastic for a variety of products, which include blood pressure cuffs, stethoscopes, and surgical instruments, and this kind of ABS injection molding should avoid recycled material absolutely.
In the packaging industry, ABS plastic is used to produce a wide range of products, including food containers, beverage bottles, and cosmetic containers.
Increasing the molding temperature will obviously reduce the heat-resistant ABS’s viscosity, increase the resin’s fluidity, and make the flow distance longer to ensure that the cavity could be filled easily.
Chemically Resistant. ABS has excellent resistance to a wide variety of chemicals, including many acids and bases. It also has good resistance to alcohols and other organic solvents. This makes ABS useful for applications where chemicals will be present in the environment around the part, such as molds for medical devices or housings for electronic equipment. Injection molding is often used for this type of application because it is an inexpensive process that can produce large quantities of parts quickly.
It is indeed a problem to completely solve the deformation problem of large-plane ABS injection molded parts. The following are some effective measures to improve the deformation:
The drying temperature of heat-resistant ABS resin is higher than that of ordinary ABS, usually 80-95℃, and the drying time is 3-4 hours.
