7. Pilot plant for plastic injection

Brand and model:Arburg, Model 420 C.

Capacity:100 tons of clamping force, 190 grams of plasticizing capacity.

Description:The injection molding machine consists of two units: injection and clamping. The injection unit is the part of the machine responsible for feeding the plastic pellets, plasticizing them, and injecting the material into the mold. Its main components are a screw, a feeding hopper, a motor, and heaters. The clamping unit holds the mold, performs the opening/closing operations, and ejects the molded piece. Its main component is the hydraulic clamping system, which is piston-type.

The machine includes molds for manufacturing test specimens to determine mechanical properties (ASTM 790, 256, and 638 standards) and to assess plastic flowability (spiral mold).
