ABS injection Molding Process

ABS-Sheet-Machine-Grade

Typical applications: automobiles (dashboards, tool hatches, wheel covers, mirror boxes, etc.), refrigerators, high-strength tools (hair dryers, blenders, food processors, lawn mowers, etc.), telephone casings bodies, typewriter keyboards, recreational vehicles such as golf carts and jet sleds.

Chemical and physical properties: ABS is synthesized from three chemical monomers: acrylonitrile, butadiene and styrene. Each monomer has different properties: acrylonitrile has high strength, thermal stability and chemical stability; butadiene has toughness and impact resistance; styrene has easy processing, high gloss and high strength. From a morphological point of view, ABS is an amorphous material.

The polymerization of three monomers produces a terpolymer with two phases, a continuous phase of styrene-acrylonitrile and a dispersed phase of polybutadiene rubber. The characteristics of ABS mainly depend on the ratio of the three monomers and the molecular structure in the two phases. This allows for great flexibility in product design, and has resulted in hundreds of different qualities of ABS materials on the market. These different qualities of materials provide different properties, such as medium to high impact resistance, low to high smoothness and high temperature distortion properties.

ABS material has super easy processability, appearance properties, low creep and excellent dimensional stability, as well as high impact strength.

Injection mold process conditions:
Drying treatment: ABS material is hygroscopic and requires drying before processing. The recommended drying conditions are 80~90℃ for at least 2 hours. The material temperature should be guaranteed to be less than 0.1%.

Melting temperature: 210~280℃; Recommended temperature: 245℃.

Mold temperature: 25~70℃. (The mold temperature will affect the finish of the plastic part, and a lower temperature will result in a lower finish).

Injection pressure: 500~1000bar.

Injection speed: medium to high speed.
