Injection Machine Screw Cylinder Replacement Parts Custom Made
PC transparent material dedicated screw and barrel is engineered for high-precision processing of PC (polycarbonate) transparent materials, including PC transparent sheets, lampshades, electronic device casings, medical equipment components and food-grade transparent packaging.
The core advantages of JCD Series dedicated screw and barrel lie in ultra-smooth surface, low material residue and high gloss retention. Its special material selection and precision processing technology avoid black spots, scratches and haze caused by material adhesion or friction, ensuring the transparency and surface finish of PC products. Compared with standard screws, it reduces defective rate of transparent PC products by 90% and maintains stable processing performance for long-term continuous production.
Our company, Dongguan Jingchuangda Machinery, is ISO 9001 & CE certified, specializing in customized screw and barrel for special materials. We have provided dedicated solutions for PC transparent product manufacturers, including suppliers of electronic device casings and medical equipment, perfectly adapting to Haitian, Zhenxiong and other mainstream injection molding machines.

Frequently Asked Questions (FAQ)
Q: How does it ensure the transparency of PC products?
A: The ultra-smooth surface (Ra ≤ 0.2μm) and low-friction material combination prevent PC material adhesion and shear-induced black spots. The precision honed barrel and superfinished screw eliminate surface defects, ensuring 95%+ light transmittance of finished products.
Q: Is it compatible with different grades of PC transparent materials?
A: Yes, it’s customizable for general PC, food-grade PC, flame-retardant transparent PC and PC/ABS blends. We can adjust screw structure and surface treatment according to specific PC material properties.
Q: What’s the lead time for customization and after-sales support?
A: 7-day rapid prototyping for small batches, 12-18 days for mass production; 6-12 months warranty is provided, with 24-hour technical response. We offer free maintenance guidance for the entire service life.
Q: How to maintain the ultra-smooth surface?
A: Avoid processing abrasive additives (e.g., glass fiber) with the same screw; clean with PP material after production to remove residual PC; periodic inspection of surface roughness is recommended to ensure product quality.
The JCD Series PC transparent material dedicated screw and barrel adopts advanced processing technology: 72-hour quenching + 168-hour vacuum nitriding + 3-stage superfinishing polishing, ensuring linearity of 0.01mm/1000mm and surface roughness Ra ≤ 0.2μm. It effectively solves the industry difficulty points of black spots, haze and poor gloss in PC transparent material processing, becoming the preferred equipment for high-end transparent PC product manufacturers.
