Understanding Plastic Sheet Extrusion Process
Learn about the advanced extrusion technology and manufacturing processes behind high-quality plastic sheets. Discover how raw materials transform into precision-engineered sheets.
Advanced Extrusion Technology
Extruded plastic sheets are manufactured through a precise process of heating and melting plastic pellets, then forming them into consistent, high-quality sheets.
We source premium plastic pellets from industry leaders including CHIMEI and Sinopec Corporation, ensuring consistent quality and performance. Our extensive material portfolio includes:
Our dual extrusion production lines enable us to create custom material combinations and multi-layer sheets, optimizing both performance and cost-effectiveness for your specific applications.
Understanding Material Shrinkage in Vacuum Forming
Material shrinkage rates are critical factors in vacuum forming mold design, directly affecting the accuracy and precision of the final product. Understanding these characteristics ensures optimal results.
Polyethylene (PE)
Shrinkage Rate: 1.6% - 3%
Requires larger mold dimensions to compensate for higher shrinkage
ABS
Shrinkage Rate: 0.4% - 0.7%
Lower shrinkage rate allows for more precise molding
Polystyrene (PS)
Shrinkage Rate: 0.4% - 0.8%
Similar to ABS, often compatible with same molds
Our engineering team precisely calculates and accommodates these shrinkage characteristics in mold design, ensuring dimensional accuracy and consistent quality in every vacuum-formed part.
Material Selection Guide
| Material | Advantages | Considerations | Applications |
|---|---|---|---|
| ABS | Excellent impact resistance, customizable properties, good moldability | UV sensitive, requires protective coating for outdoor use | Automotive parts, electronics housings, appliances |
| PS | Crystal clear, cost-effective, excellent moldability | Brittle, limited impact resistance | Display cases, packaging, disposable items |
| HIPS | Improved impact resistance, economical, easy processing | Lower clarity than PS, moderate temperature resistance | Signage, point-of-sale displays, food containers |
| Polycarbonate | Exceptional impact strength, high clarity, temperature resistant | Chemical sensitivity, higher cost, processing complexity | Safety shields, automotive lighting, medical devices |
| PETG | Easy processing, excellent clarity, chemical resistance | Not UV stable, limited outdoor applications | Medical packaging, retail displays, consumer products |
Custom Surface Textures & Finishes
Our advanced extrusion process allows for custom surface textures applied during production. Using specialized texture rollers while the material is still warm, we create distinctive surface effects that are more pronounced than mold-applied textures.
Available Texture Options
Benefits
• Scratch Resistance: Textured surfaces hide minor scratches and wear
• Enhanced Grip: Improved tactile properties for handling
• Aesthetic Appeal: Distinctive visual and tactile characteristics
• Dual-Sided Options: Textures can be applied to both surfaces
• Protective Film: Glossy surfaces include protective film during processing
Frosted Finish
Diamond Pattern
Wood Grain Texture
Electronic Texture
Glossy Surface
