The last two times have talked about these problems, to understand can click here. Causes and solutions of plastic molding shortcomings (1) The causes of and solutions to the shortcomings of plastic molding (2) 1. Deformation of finished products. Fault causes and solutions. (1) The finished product is not yet cooled when topped to reduce […]

Here are the causes and solutions described last week. The causes and solutions of the shortcomings of plastic molding (1)   1. Hairy head, flying edge.   Fault causes and solutions. (1) plastic temperature is too high to reduce the plastic temperature, reduce the mold temperature injection speed is too high to reduce the injection

Incorrect operating conditions, damaged machines, and molds can cause many molding shortcomings, and some solutions are provided below for reference. To reduce the downtime and find out the cause of the operation problem as soon as possible, the operator should record all the best injection molding conditions on the “Injection Molding Conditions Record Sheet” for

1. The basic principle of injection molding. The injection molding machine takes advantage of the nature that the plastic can melt into liquid after being heated to a specific temperature and injects the molten liquid into the closed mold cavity with high pressure. After cooling and shaping, open the mold and eject to get the

Updated November 3, 2026. Thermoset injection molding is an option to evaluate when a specified material grade and part design require a cured polymer structure. It is not inherently a process only for low-volume parts, nor does it guarantee that every part will be stronger, cheaper or faster to manufacture than a thermoplastic alternative. Potential

Clamping-area protection must be reviewed for the actual machine, mold, handling equipment and work activities. A clamp-drive description or low-pressure mold-protection function does not establish the complete personnel-protection arrangement. Separate Clamp Design from Protection Hydraulic clamping uses hydraulic-fluid pressure; describing it as air pressure in an oil cylinder is incorrect. Toggle and electrically driven arrangements

Choose an injection molding machine by matching the part, material, mold and production workflow to a documented configuration. A larger clamp, faster injection setting or higher screw speed is not an automatic improvement in part quality. Prepare the Application Brief Part drawings, critical dimensions and the exact resin grade, additives and processing information. Cavity count,

Fault management turns individual events into traceable maintenance decisions. Separate the reported symptom, confirmed cause, corrective work and verification rather than recording every event as a generic machine failure. Use a Consistent Event Record Machine and cell identification, controller and configuration where relevant. Event time, operating state, alarms and the last known acceptable conditions. Material,
