Electronic digital product moulds

Plastic shell mold--A combined Plastic mold used for compression molding, extrusion molding, injection molding, blow molding, and low foaming molding, mainly comprising a concave mold with a variable cavity composed of a concave mold composite substrate, a concave mold component, and a concave mold composite card board, and a convex mold with a variable core composed of a convex mold composite substrate, a convex mold component, a convex mold composite card board, a cavity cutting component, and a side cutting composite board. Coordinate changes in mold convex, concave, and auxiliary forming systems. Can process series of plastic parts of different shapes and sizes.

Plastic Mould  Start from part design analysis.
Possible causes of problems
(1) Insufficient injection speed.
(2) There is a shortage of plastic.
(3) The screw did not leave any screw padding at the end of the stroke.
(4) Change in operating time.
(5) The temperature of the injection cylinder is too low.
(6) Insufficient injection pressure.
(7) The nozzle is partially sealed.
(8) The heater outside the nozzle or injection cylinder cannot operate.
(9) The injection molding time is too short.
(10) Plastic is attached to the throat wall of the hopper.
(11) The capacity of the injection molding machine is too small (i.e. injection weight or plasticizing capacity).
(12) The mold temperature is too low. (13) The anti rust oil on the mold was not cleaned thoroughly.
(14) The stopper ring is damaged and there is a backflow of molten material.
