Handle Flange XT2 Precision Molded Plastics Injection Molding

The mold manufacturing process and product material selection of plastic products are key factors to ensure product quality and production efficiency.
Mold manufacturing process:
a. Mold design: Design the mold according to the shape, size and requirements of the plastic product. Mold design includes mold structure design, filling system design, cooling system design, demoulding system design, etc.
b. Material preparation: Select suitable mold material, such as tool steel or stainless steel. According to the mold design, prepare the required materials, including mold base plate, mold cavity, mold core and other parts.
c. Processing mold parts: Process mold parts according to the mold design. Including cutting, milling, drilling, turning and other process operations to manufacture various parts of the mold.
d. Heat treatment: Heat treatment of mold parts to improve the hardness and wear resistance of the material. Common heat treatment methods include quenching, tempering, etc.
e. Assemble the mold: Assemble the processed mold parts, including the assembly of the mold base plate, mold cavity, mold core and other parts. Ensure the accuracy and stability of the mold’s structure and size.
f. Debugging and mold trial: Carry out debugging and mold trial on the assembled mold. Use the injection molding machine to test the mold, observe and detect the filling performance of the mold, the size and quality of the product, etc.
g. Surface treatment: Surface treatment of the mold to improve the corrosion resistance and appearance quality of the mold. Common surface treatment methods include electroplating, spraying, etc.
h. Mold maintenance and upkeep: During the use of the mold, clean, lubricate and maintain the mold regularly to extend the service life of the mold. Reasonably arrange the replacement and repair of molds based on production volume and usage.
Product material selection:
a. Injection molding material: Select the appropriate injection molding material according to the requirements of the plastic product and the application environment. Common plastic materials include ABS,PP,PC,ABS/PC,PBT,PMMA,SAN,PA,PA66,PA6,POM,PET,PE,PVT,TPE,TPR,SILICONE,PEEK,PEI,PS,PES,PI,PPSU,PETG,PCTG,PFA,NBR,PTFE,PAEK,PAA,PEAA etc. According to the characteristics and requirements of the product, select materials with appropriate hardness, wear resistance, chemical resistance and other properties.
Mold material selection:
The selection of mold materials should take into account the shape, size and requirements of the plastic product, as well as the service life and production volume of the mold. Common mold materials include tool steel, stainless steel,738、2738H 、718、718H、NAK80、2083、2316、2344、2083H、2316H、S136、S136H、S136-D、HPM38、M300、S-STAR、M333、S196 etc., which have high hardness and wear resistance.
