Recycled Material Injection Molding | From Switching Considerations to Optimization of Molding Conditions
When asked, 'What is the ratio of recycled materials?', we will consider the use of recycled materials together from the perspectives of materials, design, and molding.
In April 2026, the revised Resource Effective Utilization Promotion Law will be enacted, requiring major manufacturers of automobiles, home appliances, and packaging to develop plans for the use of recycled plastics and to provide regular reports. There has been an increase in inquiries from parts manufacturers and molding manufacturers asking questions like, "What is the recycled material ratio for this part?" and "Can we switch to recycled materials?" Recycled materials tend to have variability in physical properties, are prone to degradation due to heat, and can easily warp or shrink, making it insufficient to simply replace virgin materials. Our company leverages over 70 years of experience in resin molding to support the utilization of recycled materials. 【Features】 ■ Consideration for switching to recycled materials: Assessing usability and mixing ratios in light of required strength and appearance. ■ Innovations in molding conditions and molds: Reviewing molding conditions to match fluidity and variability. ■ Proposing technologies to reduce warping and shrinkage, such as gas injection (AGI molding method). ■ Design for recyclability: Reducing the number of parts, using single materials, creating easy-to-disassemble structures, and material labeling. ■ Proposing materials that reduce petroleum-derived plastics, such as 100% biomass materials. *Please feel free to consult us even if you are at the stage of "not knowing where to start."
basic information
■Response Content - Consideration of switching to recycled materials (PCR, PIR) and examination of mixing ratios - Optimization of molding conditions and measures for molds - Proposals for designs that facilitate recycling (reducing the number of parts, using single materials, easy disassembly structures, material labeling) - Proposals for alternative materials such as 100% biomass materials ■Molding Equipment - Injection molding machines: 20t to 450t - Clean booth (constant temperature and humidity) compatible: below 230t ■Main Molding Technologies - Gas injection (AGI molding method) - Injection compression molding / partial compression molding - Thin-walled molding / automatic insert molding ■Applicable Fields Automotive parts / home appliance parts / container packaging / industrial equipment parts, etc. ■Consultation Process Hearing → Proposal for feasibility of switching and ratios → Prototyping and evaluation → Mass production There are three additional items that can improve the response if included. If you can provide information within your knowledge, I will add them to the above proposal. Applicable Resins: Types of resins that can be molded with recycled materials, such as PP, ABS, PC, PA, etc. Applicable Lots: The extent of quantities that can be handled from prototyping to mass production. Molded Product Size: Guidelines for the maximum and minimum dimensions that can be accommodated.
