Here are its specific application scenarios and benefits:
Target Materials
PC (Polycarbonate): E.g., automotive lamp housings, dashboard components, electronic/electrical enclosures (requiring lightweighting, thermal/acoustic insulation), building materials (hollow sheets).
PET (Polyethylene Terephthalate): E.g., foamed sheets (food packaging trays, insulating mats), foamed preforms (lightweight beverage bottles), engineering parts (requiring rigidity and lightweighting).
PBT (Polybutylene Terephthalate): E.g., electrical connectors, automotive components (requiring heat resistance, flame retardancy, lightweighting), tool handles.
Application Processes
Producing various structural foam parts like enclosures, housings, brackets, containers, tools.
Especially effective for solving injection molding issues: Eliminating surface sink marks, shortening cooling time (thus reducing overall cycle time), improving product appearance (smooth surface).
Producing foamed sheets, boards, profiles, tubes.
Manufacturing foamed films.
Creating microcellular foams in cable insulation layers to enhance performance.
Extrusion Molding
Injection Molding
Application Goals / Key Benefits:
Shorter Injection Molding Cycle: The insulating effect of the foamed core reduces cooling time, shortening the overall injection cycle and boosting output.
Eliminates Sink Marks: A critical application point in injection molding, particularly for parts demanding high surface quality (e.g., automotive interiors, electronics housings).
Smooth Surface Finish: Moisture-free decomposition and uniform cells prevent surface defects like streaks, silver marks, or blemishes caused by moisture vapor or coarse cells, resulting in a smooth, dense surface skin.
Lightweighting: Significantly reduces part density and weight by introducing a uniform, fine cellular structure, saving material costs.
Thermal/Acoustic Insulation: The gas-filled cell structure effectively blocks heat flow and sound waves, suitable for components requiring thermal/cold retention or noise reduction (e.g., packaging, building materials, automotive parts).
Material Cost Savings: Reduces resin consumption while maintaining or approaching original performance.
Improved Dimensional Stability: Foaming helps reduce internal stress, thereby minimizing shrinkage and warpage, especially beneficial for large parts or parts with significant wall thickness variations.
Enhanced Surface Appearance:
Increased Production Efficiency:
Cushioning & Impact Absorption: The cellular structure offers good energy absorption, suitable for packaging materials or parts requiring shock absorption.
Lower Dielectric Constant: Foamed plastics have a lower dielectric constant than solid plastics, advantageous in some electrical/electronic applications.
Target Industries:
Automotive: Interior parts (door panels, dashboard components), exterior parts, functional parts (insulation pads), lamp housings.
Packaging: Food trays, insulated take-out packaging, protective packaging, lightweight preforms/containers.
Electronics & Electrical Appliances: Equipment housings, connectors, bobbins, electronic component brackets.
Building & Construction: Insulating/ soundproofing panels, profiles, decorative moldings.
Sports & Leisure Equipment: Helmet liners, buoyancy materials, equipment parts.
Industrial Goods: Tool handles, material handling crates/pallets.
Summary of Key Application Points
Core Value: Provides high-temperature, moisture-free, high-quality foaming capability for PC, PET, PBT.
Primary Processes: Extrusion and Injection Molding.
Standout Advantageous Applications:
Significantly eliminating surface sink marks, enhancing appearance grade.
Achieving a smooth, blemish-free surface.
Shortening the injection molding cycle, improving production efficiency.
Extrusion: Producing high-quality foamed sheets/boards/profiles with fine, uniform cells.
Injection Molding:
Achieving part goals: Lightweighting, thermal/acoustic insulation, cost savings, improved dimensional stability.
