Main Benefits

  • Explosion-Proof Electronics for Safety: The equipment offers electronic options that include motors and controls compliant with industry standards for explosion-proofing. This provides a safer working environment and ensures compliance with industry safety regulations, which is crucial for maintaining operational licenses and avoiding legal liabilities.

  • Punch Restrainers for Uniform Quality: Punch restrainers are employed to control the movement of lower punches, thereby enhancing tool durability, ensuring uniform compact weight, and reducing the occurrence of double logo impressions. This results in more consistent product quality and a reduction in product rejections.

  • Adjustable Upper Rolls for Tool Longevity: Adjustable upper rolls are incorporated to increase the lifespan of tools and aid in the formation of compacts across various die levels. This not only extends tool life but also ensures optimal compact formation, enhancing product quality.

  • Versatile Core-Rod System: The core-rod system is capable of creating compacts with either blind or through-holes. This versatility allows for a wider range of product designs, opening up more market opportunities.

  • Precision with Keywayed Punch Sockets: The punch sockets are keywayed, providing accurate alignment for tooling of irregular shapes. This feature ensures precision in tablet shaping, reducing waste and improving product consistency.

  • Shadow Fill Systems for Efficiency: The shadow fill systems are designed to reduce punch stroking and use recirculated granulation, ensuring consistent compact weight and cleaner operations. This leads to higher quality products and a cleaner, more efficient production environment.

  • Abrasion-Resistant Die Table Surface: The die table surface features a hardening treatment resistant to abrasion and includes removable bushings for both upper and lower punches. This enhances the durability and longevity of the machine, making it more cost-effective in the long run.
