Mold validation stages Does the mold work? Activities during this phase relate to the validation of the injection mold’s mechanics. The mold is mounted into the press and dry-cycled (no resin is injected) to ensure it opens and closes normally at operational temperature. […]
Time and cost are becoming more and more important factors in the development of new products. It is therefore extremely important for the injection molding industry to produce prototypes that can go into production as quickly as possible. […]
Avoid interrupted cuts. Because the tungsten carbide head is fairly brittle, a gun drill should always cut into solid material to avoid breaking of the cutting edge. […]
the mold industry lays great emphasis on efficiency. Sometime, considering the credit therein, even when business negotiation between the manufacturing and the customers is still under way, […]
when molding plastics of particularly large abrasion force, the abrasion may still be rather serious even if high carbon or high chrome is used. […]
plastic mold parts fall into working parts and structural parts, working refer to those determining the geometrical shape, dimension and precision of plastic products, and are also called molding parts or the molding section of parts, such as cavity, core, insert, molding pin and molding ring etc, their molding condition is rather complicated and the [...]
cooling at the gate part should be intensified, for cooling only, avoid setting the medium channel at the welding mark of the plastic parts, whereas the heating of medium channel should be preferably near the welding mark. […]
the cores and cavity molds should be separately controlled, generally, cavity molds absorb more heat and contain large heat radiating area, and therefore, require stronger control than cores. […]
the hot and cold medium channel of molds is usually in hole or slot form, […]
temperature of plastic molds directly influences the molding quality and productivity of plastic parts, for thermoset plastics, […]
