Polycarbonate injection molding parts manufacturing solution
Polycarbonate injection molding resin is one of common engineering resin.
Three major application areas of polycarbonate engineering plastics is a glass assembly industry, automobile industry and electronic, electrical industry, followed by industrial machinery parts, CD, packaging, computers and other office equipment, medical and health care, computers and other office equipment, medical and health care, film, leisure and protective equipment etc.
Polycarbonate can be used as the glass doors and windows, polycarbonate laminates are widely used in protective window bank, embassy, detention and public places, for aircraft cockpit, lighting equipment, industrial safety baffle and bulletproof glass.
Polycarbonate resin used in car camera system, instrument panel system and interior system such as front cover, reinforced with automobile front plate, the reflective mirror frame, door sets, operating rod sheath and resistance flow plate.
Polycarbonate is used as a junction box, socket, plug and sleeve, gasket, TV conversion device, connecting line bracket lower communication cable, switch box, telephone switchboard, switchboard element, relay case.
Polycarbonate can be used with low load parts, household appliance used for motors, vacuum cleaners, washing machine, Coffee machine, baking bread machine, power tool handle, all kinds of gear, worm gear, shaft sleeve, guide, the refrigerator shelf.
Polycarbonate bottle (container) have very good performance such as transparent, light weight, impact resistance, high temperature resistance and corrosion solution etc.
Polycarbonate and Polycarbonate alloy can be used as a computer frame, shell and auxiliary equipment, printer parts. Modified polycarbonate with high energy radiation sterilization, boiling and baking disinfection can be used for blood sample apparatus, blood oxygenator, surgical operation instrument and kidney dialyzer etc.
Polycarbonate can be used for helmets, protective masks, sunglasses and sports goggles.
PC film is widely used for printing chart, pharmaceutical packaging, film type commutator.
Polycarbonate injection molding process
This is general polycarbonate injection molding process. During your polycarbonate injection molding, you should read your resin specification, your products and mold design from your polycarbonate molding supplier to set up the injection molding parameter. You can always find the the resin specification on IDES.com
|Poly carbonate Drying Before molding||PC resins are hygroscopic and pre-drying is important. Recommended drying conditions are 100 – 120 C (212 – 248 F) for 3 to 4 hours. Moisture content must be less than 0.02% prior to processing.|
|Polycarbonate Molding Melt Temperature||260 – 340 C (500 – 644 F); higher range for low MFR resins and vice-versa|
|Mold Temperature For Polycarbonate Molding||70 – 120 C (158 – 248 F); higher range for low MFR resins and vice-versa, On the PC molding process, we should prepare hot oil supplies or hot water supplies fortemperature control.|
|Fill Pressure||As high as possible for rapid molding|
|Injection Speed||Slow injection speeds when small or edge gates are used; high speeds for other types of gates|
Steel choice for transparent polycarbonate injection mold
You should choose 420 series stainless steel for polycarbonate injection mold. There are lots of kind of 420 series stainless steel. If you need the surface finishing higher than SPI A3, you had better to choose the ASSAB S136 and NAK80. If it is SPI A3, you can choose LKM 420. You can also see the injection mold steel post on our blog to know more for the mold steel choice.
Steel choice for opaque polycarbonate injection mold
You can choose the mold steel as the normal injection mold. Please be sure that you will not switch to have the plastic injection mold life“.molding products from this mold. Please read more details for the mold steel choice based on on post “
