How to solve the bubble of PC plastic injection molding process a. The wall thickness should be as uniform as possible b. Transition part should be gradually, smooth transition c. Gate. The runner is as wide and thick as possible d. Die surface should be smooth and low e. Vent.

Elimination method of under-injection defect: 1.materials 2.mold design 3.injection molding machine 4.Process conditions 5.part design

Five steps of hydraulic system maintenance of injection molding machine 1.Hydraulic oil quality 2.Hydraulic oil temperature 3.Oil quality of hydraulic oil 4.Cleaning of oil filter 5.Cooler cleaning

3. The melting speed is too fast even if 180℃ injection will also be plastic.

These three points are important processes that affect the strength of injection molded parts 1. Increasing the injection pressure can improve the tensile strength of PP injection parts. 2. Mold transport hot oil injection can improve the strength of copper parts and nylon parts.

Which 5 kinds of engineering plastics can be replaced by polyformaldehyde(POM)? 1. Polyester(PET) 2. Makrolon 3. Polyamide 4. Polyphenylene Sulfide(PPS) 5. Polytef

Debugging elements of forming process 1. Forming temperature 2. Blow air pressure 3. Mold temperature 4. Needle design and insertion speed 5. Dimension and surface quality of mouth and core die 6. Clamping speed

7 Necessary considerations of injection molding process 1. The shrinkage rate 2. Flowing property 3. Crystallization 4. Heat sensitive plastics and easily hydrolyzed plastics 5. Stress cracking and melt rupture 6. Thermal propeties and cooling rate 7. Hygroscopic

Notes for mold storage II 3. The mold should not be placed unsteadily to prevent the mold from being damaged or causing safety accidents. 4. The mold can not be placed randomly.

Notes for mold storage I 1. Do not store the mold in the humid, corrosive, high temperature, dust bad environment. 2. Do not pile other items and parts in the mold cavity and incision and other important parts.

Forming process debugging of square stacking bucket

Detailed explanation of the proximity switch of the blow molding machine 1. How many types of proximity switches? 2. How does the high-frequency oscillation type proximity switch detection work? czplasticfactory.com/detailed-expla…

Precautions for use and maintenance 2. Any contamination of the mold cavity is forbidden to ensure that its surface quality is at a high level. 3. When replacing mold seals, high-temperature-resistant seals should be selected, and the temperature-resistant grade should be ≥200℃

Precautions for maintenance of blow molding product molds 1. When the mold temperature is controlled by mold temperature machine, because the mold temperature is correspondingly high, the maintenance personnel should pay attention to prevent burns and ensure safe operation.

Happy International Labour Day!
