Elevating the quality of recycled resin for home appliances with Kopleon equipment to the next stage.
Double treatment with a two-axis extruder and silo deodorization fundamentally solves the odor of recycled resin.
In the home appliance industry, while the use of recycled resins is advancing in the manufacturing of enclosures, the odor from raw materials has become a quality-related issue. Reducing odor is an important factor as it directly impacts product safety and user experience. Our company effectively reduces the unique odors of recycled materials by combining the melting and deodorization processes using a twin-screw extruder with aging and deodorization processes in silos, contributing to the improvement of the quality of home appliances. 【Usage Scenarios】 - Odor reduction of recycled resin pellets used for home appliance enclosures - Expansion into a wider range of applications through improved quality of recycled materials - Enhancement of product safety and user experience 【Effects of Implementation】 - Stable supply of low-odor recycled resin pellets - Increased value of recycled materials and strengthened market competitiveness - Contribution to reducing environmental impact

basic information
【Features】 - Deodorization using a twin-screw extruder: By achieving high shear and mixing performance, it uniformly melts the resin while efficiently removing odor components through the addition of water and a vacuum venting mechanism. - Finishing through silo deodorization: The pellets after extrusion are carefully ventilated and matured within the silo, gradually releasing even trace amounts of residual odor components. - Effective odor reduction through two-stage processing: It combines immediate deodorization during the process with the removal of residual odors over time. - Availability of lab equipment: Testing and evaluation before implementation are possible. - Collaboration with Herbold cleaning equipment: One-stop manufacturing from the cleaning of recycled materials to pelletizing is achievable. 【Our Strengths】 Kobelco Kasei Co., Ltd. provides products based on over 65 years of rich know-how and experience as a pioneer in co-rotating twin-screw extruders. With a proven track record in the fields of plastics, food, and batteries, we are a comprehensive manufacturer that handles everything from technical proposals tailored to customer needs to turnkey plants. Testing of twin-screw extruders within Japan is also available through DJK Co., Ltd.
