Factors of injection molding
1. Temperature: barrel temperature, material temperature, mold temperature, drying temperature, oil temperature, environment temperature, etc
2, pressure: injection pressure, holding pressure, back pressure, demoulding pressure, mold opening pressure, mold locking pressure, etc
3, Time: injection molding time, holding time, cooling time, drying time, metering delay time, etc
4, speed: injection speed, return speed, open and close die speed, demoulding speed, etc
5, stroke: metering stroke, demoulding stroke, die stroke, etc
In injection molding, these elements are interrelated and can not be set independently, but to shape the product,
The type of resin, mold structure and other relations, are considered, according to the best state of injection molding for setting
In the setting of forming conditions, how to carry out the best setting and product defect is how to change the setting is a comparison
More difficult, because all the factors are interdependent. Some factors contribute more to a defect, others less, and
I
It’s also different for different materials
Improper operating conditions, broken machines and molds can produce many defects in forming. Here are some solutions
Fyi, in order to reduce downtime and to find out the cause of the problem as soon as possible, the operator should put the best injection molding conditions
Record on “injection molding condition record sheet” for future reference when solving problems.
