Know: "foaming mold"

Foam molding mold is a plastic foam mold.

Foaming mould English: foaming mould.

The foaming resin is directly filled into the mold, and it is heated and melted to form a gas-liquid saturated solution. Through nucleation, a large number of tiny nucleus nucleuses are formed and the nucleus grows to form a foamed plastic part. There are three commonly used foaming methods: physical foaming, chemical foaming and mechanical foaming.

The die has a streamlined runner surface. The two-part die body design allows the die to dismantle and is easy to clean. Manually fine-tune the elastic lip or movable upper die lip design to suit the different thickness requirements of the extruded sheet. The vertical or oblique 45° choke bar design is evenly distributed to accommodate different viscosity melt streams. The mold body is made of high-quality mold steel or imported alloy steel to extend the life of the mold.

● The surface of the runner is plated with hard chrome, with an average thickness of 25μm to 50μm, and mirror polished.

● Die fasteners are 12.9 high-strength bolts.

● The heating elements are high quality, durable stainless steel heating rods and heating rings. PVC mould

1: After the mold is used for a long time, it must be sharpened. After grinding, the edge surface must be demagnetized, and it must not be magnetic, otherwise the material may be easily blocked.

2: Springs and other elastic parts in the use of the most vulnerable to damage to the spring, usually the phenomenon of fracture and deformation. The method adopted is replacement. During the replacement process, attention must be paid to the specification and model of the spring. The specification and model of the spring are identified by the color, outer diameter, and length. Only when all three items are the same, can they be replaced.

3: The punch is prone to breaking, bending and smashing during the use of the die. The punching sleeve is generally damaged. Damage to punches and bushings is generally replaced with parts of the same specification. Punch parameters mainly include working part size, mounting part size, and length dimension.

4: Fasten the parts and check if the fastening parts are loose or damaged. The method is to replace the parts with the same specifications.

5: Pressing parts such as pressure plate, excellent glue, unloading parts such as stripper plate, pneumatic top material and so on. During maintenance, inspect the parts and their parts for damage, repair the damaged parts, check the pneumatic top material for leaks, and take measures for specific conditions. If the air tube is damaged, replace it.
