What is direct injection in safety footwear manufacturing process?

Tsimba safety footwear is made through the direct injection process. Direct injection (DI) is a manufacturing process for safety footwear that involves injecting molten polyurethane (PU) directly into the upper and outsole of the shoe. This process has several advantages over traditional methods of manufacturing safety footwear, such as:


  • Durability: The DI process creates a single, seamless unit between the upper and outsole, which makes the shoe more durable and resistant to wear and tear.
  • Comfort: The DI process allows for the use of softer, more flexible PU materials, which can make the shoe more comfortable to wear.
  • Lightweight: The DI process can produce shoes that are lighter than those made using traditional methods.
  • Precise fit: The DI process can produce shoes that have a more precise fit, which can improve comfort and safety.
  • Resistant to chemicals and oils: The DI process can produce shoes that are resistant to chemicals and oils, which can make them suitable for use in hazardous environments.


Overall, the DI process is a versatile and efficient manufacturing process that can be used to produce high-quality, durable, and comfortable safety footwear.


Here are some additional advantages of the DI process:


  • Reduced waste: The DI process produces less waste than traditional methods of manufacturing safety footwear. This is because the PU material is injected directly into the mold, which eliminates the need for cutting and trimming.
  • Faster production times: The DI process can produce shoes more quickly than traditional methods. This is because the PU material is injected directly into the mold, which eliminates the need for multiple steps.
  • Improved quality control: The DI process can produce shoes with more consistent quality. This is because the PU material is injected under controlled conditions, which minimizes the risk of defects.


As a result of these advantages, the DI process is making the Tsimba safety footwear the best brand of choice.
