ABS is an acronym for Acrylonitrile Butadiene Styrene) is a thermoplastic polymer material with high strength, good toughness, and easy processing and forming. Because of its high strength, corrosion resistance, and high temperature resistance, it is often used to make plastic casings for instruments.
Many friends who wear glasses will know that today's spectacle lenses are a kind of resin material, which is lighter and more comfortable, and ABS is an enhanced version of it. So what exactly does ABS do? Next, I will explain it to you. ABS resin, ABS is the acronym for Acrylonitrile Butadiene Styrene) is a thermoplastic polymer material with high strength, good toughness, and easy processing and forming. Because of its high strength, corrosion resistance, and high temperature resistance, it is often used to make plastic casings for instruments.

ABS prototype sample
 
1. The molding characteristics of ABS are:
a. Amorphous plastic, strong hygroscopicity, should be fully dried;
b. Medium liquidity, overflow value: 0.04mm;
c. It is advisable to use high material temperature, high mold temperature, and high injection pressure;
d. The mold gating system should have low resistance to material flow. It should be noted that the position and form of the gate should be selected, and the demolding angle should be 20 or more.
 
2. Response measures
a. ABS is easy to absorb water, so it should be dried before molding.
b. Strictly control the processing and assembly accuracy of molded parts such as cavity and core.
c. Use the corresponding screw injection machine to preheat the mold when conditions permit.
d. Check the information, the mold uses one mold and two parts, the mold uses point gates, and the main runner has a circular cross section to reduce frictional resistance and design a suitable gate position.

ABS prototype is one of the most common prototypes, accounting for about 80% of the total number of prototypes. This is because ABS is a relatively good engineering plastic, and its strength can well meet the needs of various types of prototype processing. Such as testing functions, polishing and coloring. It is easier to polish the ABS material, and the smoothness of the surface is guaranteed. Generally, if you need to color and silkscreen the surface after making the prototype, the surface should be sticky and not too slippery. Otherwise, it will be difficult to spray oil and silk screen without sticky glue!
