Texin Overview

What is Texin?

You encounter Texin as a thermoplastic polyurethane, often called TPU. Manufacturers create Texin by reacting diisocyanates with short-chain and long-chain diols. This process forms a block copolymer with alternating hard and soft segments. You can adjust the ratio and structure to produce TPUs with different properties. Texin stands out because it combines flexibility, durability, and chemical resistance. You see Texin used in many industries, from automotive to consumer electronics. Its versatility makes it a popular choice for plastic injection molding.

Tip: You can select Texin for applications that need both strength and flexibility.

You benefit from Texin’s ability to handle high injection pressure without losing shape or strength. This property helps you create durable products that last longer and perform better. You also reduce maintenance costs because Texin resists wear and tear inside plastic injection molds.

Texin and Injection Molding Machines

Processing Texin

You work with Texin in an injection molding machine by following precise processing steps. You must dry Texin thoroughly before molding to prevent moisture problems. For best results, dry the resin at 150°C for at least four hours or at 170°C for three to four hours. You also need to pre-dry PVC resin at 60°C for two to three hours to avoid bubbles and voids.

When you set up your injection molding machine, you control several parameters to achieve consistent quality. The table below shows the recommended settings:

You notice that a fast fill reduces cycle time and improves part quality. You also monitor nozzle temperature, which should be 10–20°C lower than the barrel. Careful temperature management helps you avoid defects such as incomplete fill, burn marks, and surface imperfections.

Technical challenges often arise during processing. You may encounter uneven plasticization or cooling rate discrepancies in the die cavity. You address these issues by using advanced technologies like AI optimization and annealing products to relieve internal stress. Careful control of your injection molding machine ensures high-quality results and efficient cycle time.

Design Considerations

You must consider several design factors when using Texin in an injection molding machine. Uniform flow is essential, so inject the melt slowly to allow trapped air to escape. Use a generous draft and taper of at least 2° on part walls to make mold release easier. If you need mold release agents, choose non-silicone types such as dry fluorocarbon to maintain performance.

Wall thickness plays a key role in product strength. Thicker walls provide greater pull-out and torque resistance. You also design parts to minimize defects. Incomplete fill and burn marks often result from trapped air, so proper venting and slow injection help prevent these issues. Surface imperfections can occur if venting is poor, leading to blisters or uneven finishes.

Tip: You improve cycle time and reduce defects by optimizing mold design and processing parameters in your injection molding machine.
