The shrinkage rate of plastic reflects the degree of dimensional reduction in a plastic part after it is removed from the mold and cooled. Factors affecting plastic shrinkage include the type of plastic, molding conditions, and mold structure. Different plastics exhibit varying shrinkage rates. Additionally, the shrinkage rate is significantly influenced by the part's shape, complexity of internal structure, and the presence of inserts.

Injection molding often encounters burn marks, a critical defect that severely impacts product appearance and quality. This article deeply analyzes the root causes of burn marks and proposes systematic countermeasures.

PES is a high-performance specialty engineering plastic. Thanks to its unique molecular structure, it maintains excellent mechanical strength and dimensional stability even under long-term high-temperature environments (above 180°C). It also offers transparency, hydrolysis resistance, flame retardancy, and is BPA-free. Widely used in medical devices (e.g., reusable sterilizable instruments), electronics (high-temperature connectors), and automotive components, PES is a critical material for high-end industrial and technological products.

BASF Ultramid® A 50H1 is a high performance PA66 grade based on a halogen free and phosphorus free flame retardant system. It achieves V 0 flammability rating while retaining the excellent mechanical strength and processability typical of polyamides. With a tensile modulus of 3800 MPa and good low temperature toughness – remaining robust even at –30°C – it resists brittle failure in harsh environments.

The Middle East conflict has disrupted Strait of Hormuz shipping, posing major challenges for imported engineering plastics including supply shortages, price surges, and extended lead times. We recommend extending procurement cycles, diversifying sources, and partnering with a professional trading company to mitigate risks and ensure stable supply.
