HASCO introduces new products for better molds

The new HASCO thermal insulating sheets Z1215 for external insulation prevent heat from escaping from heated injection and compression molds. They have been specially developed for molds that are subject to a high level of thermal stress.

According to HASCO's information, molds can be fully insulated using this thermal insulating sheet, which is made of high-temperature plastic. The sheets are placed against one side of the mold, with their honeycomb structure forming insulating air chambers, ensuring considerable energy savings both during the heating phase and throughout the injection molding process.

The new thermal insulating sheets are available in a large number of dimensions and can also be supplied in custom sizes. The Z1215 sheets display very good resistance to release and cleaning agents. For a simple screw connection, HASCO recommends using its countersunk screws Z330.

External insulation of the mold with "inside hot - outside cold" also has a number of advantages for the operator in respect to occupational safety. Safe handling is possible, since there is less risk of injury through burns. Selective use of innovative thermal insulation with A1215 makes it possible to avoid the loss of valuable energy and improve on the quality of the plastic parts - a sustainable and highly profitable investment, said HASCO.

Also introduced by HASCO are the company's new shoulder guide screws Z382 with g6 tolerance, used primarily to guide ejectors or stripper plates. The screw-in guide pillar with a ground d1 fitting dimension is available in four different lengths. It has been designed especially for use in H7 guide bushings.

By using the shoulder guide screw it is possible to ensure precise guidance of ejectors. Maximum process reliability serves to boost production quality, said HASCO.
