The modifications of PBT mainly include flame-retardant PBT, glass fiber-reinforced flame-retardant PBT,? and glass fiber-reinforced PBT. PBT is commonly blended with PC to form alloys used in automotive parts, with PC/PBT often utilized for car bumpers. Additionally, modified PBT can be used for car window motor housings, motorcycle motor parts, and automotive transmission gearboxes.

PBT Products Quality Assurance
The quality of PBT plastic fabricated products is inseparably linked to the quality of the raw materials used. We have stable suppliers with whom we’ve cooperated for over a decade, and we can provide quality inspection reports for any raw materials. We can also purchase from suppliers you specify and provide proof of purchase.
Advanced Mold Testing
FirstMold conducts mold fitting and mold polishing for every set of molds and performs mold testing using precision CNC machines, precision injection molding machines, and mold fitting machines.
In-Process Quality Checks
FirstMold implements 6S management on-site, promptly addressing any issues that arise at each stage. Injection molding production also includes timely spot checks, along with immediate preventive measures and quality control adjustments.
Final Inspection and Testing
Comprehensive final quality inspections are conducted using professional testing equipment, including coordinate measuring machines (CMM), height gauges, moisture analyzers, pressure gauges, and color controllers, to ensure the utmost quality.
