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.

Quality Assurance

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.

Advantages of ABS injection molding

Through the various features of ABS injection molded parts, we can easily understand the multiple advantages of ABS injection molding.

Durability and Precision: ABS injection molded parts provide the necessary impact resistance, dimensional stability, and precision required for components like dashboards and bumpers, durable casings and intricate components.
Aesthetic Versatility: These parts can be finished to a high-quality appearance, suitable for toys and appliances that require an attractive look, as well as healthcare devices where functionality combines with user-friendly design.
Cost-Efficient Production for High-Volume Industries: The ease of processing and recyclability of ABS make it ideal for industries like construction and packaging, where cost efficiency and the ability to produce large quantities of durable, precise parts are critical.

According to statistics, ABS material has the highest usage rate in all injection molding projects at FirstMold.
