The repelletizer machine recycles pellets from the mini runner (sprue runner), regrinds and returns to the hopper of the injection molding machine.

Features of Repelletizer Machine

  • Touch screen controller makes operation and troubleshooting easy.
  • Output pellet quantity: 5kg to 10kg per barrel. Actual output may differ depending on type or resin and operating conditions, etc.
  • Size of the pelletized resins can be adjustable according to requirements.
  • Developed unit and works well for all types of resins.
  • It is a hot cutting machine with no water cooling system required.
  • Air cooling system makes material appraisal (Tensile strength, Stretch, Flexural strength, Flexual elasticity, Melt Flow index) for recycled pellets better than water cooling.
  • Equipment costs easily justified by material savings.
  • Process temperature required is 10% lower than material melting temperature.
  • Properties of pellets resin are same as crushed material.

Twin Head Repelletizer Machine

  • Two types of Resins can be produced at the same time.
  • Double the usual capacity.

The total cost saving solution

Repelletizer machine:

  • Fewer manpower to handle the process
  • Able to regrind and pelletize crushed mini-runner to the same size as virgin material.
  • As such, the pellets will be evenly mixed and melted ensuring even quality.
  • 0% wastage. All waste materials can be recycled unlike crushed materials.
  • Lesser virgin material required as recycled material is able to produce equally good quality products.
  • Lower investment with greater returns.
Description
Crushed Material Pelletized Material Cost savings
Recycle waste material based on 3 tons/mth 50% of powder to be thrown. Only 1.5 tons of material can be used 0% powder to be thrown. 3 tons of material can be used.  
LCP USD17/kg x 1500kg = USD 25,500/mth Investment based on 3 years + approximate electricity cost = USD 1,700/mth USD23,800/mth
