VALUE SOLUTION Improve safety and reduce costs with Gravi-Tech formulations When Gravi-Tech polymer metal composites are substituted for lead, manufacturers can avoid the regulatory, disposal and employee exposure challenges associated with lead. If the material is shear-sensitive, consult the material data sheet or processing guide for instructions to set recovery time • The cooling time should only be 1–2 seconds longer than the screw recovery time, unless dictated by dimensional stability or part thickness Minimize Clamp Pressure This step is done to reduce the amount of energy used by the machine. • Reduce the clamp tonnage until flash is seen around the parting line, then increase the clamp tonnage by 5-10% Minimize Cycle Time • Mold Open/Close – Should be as fast as possible, without slamming, and still produce a nice fluid motion • Ejector Speed – As fast as possible, without influencing part quality • Ejector Stroke – Only stroke the ejectors as many times as needed to separate the part from the core - i.e.
