Market trends: Lightweight, high complexity, and aesthetic integration

From new energy vehicles to wearable smart terminals, product structures are becoming increasingly complex and appearance requirements are getting stricter. The industry has put forward three new demands for plastic raw materials:

✔ Lightweight, cost reduction and carbon emission reduction

✔ Thin-walled complex structure design

✔ High surface quality and functional integration

Traditional ABS and PC monomer resins are difficult to balance all aspects, and ABS Polycarbonate Plastic PC-345 is precisely the preferred composite material to address this trend.

Chi Mei PC-345

01 | Material highlights: Performance advantages of PC-345

🔹 high fluidity, breaking through design limitations

Optimize the flow formula, enhance the mold filling effect, and be suitable for ultra-thin, microstructure, and complex geometry products.

🔹 low shrinkage, ensuring dimensional stability

Effectively reduce the risk of deformation and stress cracking, and meet the requirements of high-precision assembly.

🔹 Good processability, improving production efficiency

It comes with a self-lubricating demolding agent, which shortens the injection molding cycle, extends the service life of the mold, and reduces the overall cost.

🔹 has excellent comprehensive mechanical properties

Combining the toughness of ABS with the rigidity of PC, it ensures that the products have excellent impact resistance and durability, and are suitable for a wide range of demanding applications.

02 | Process compatibility

✔ It is suitable for high-speed injection molding and can meet the rapid mass production requirements of thin-walled and complex parts

✔ Supports high-precision mold matching to ensure appearance and assembly accuracy

✔ It can be processed a second time, such as surface coating, electroplating, printing, laser engraving, etc
