Key Materials Used in Blow Molding
The choice of plastic resin is integral to the performance and application of blow molded products. Leshan machines are compatible with several common and specialized materials:
undefined
| Material | Properties | Common Applications |
|---|---|---|
| HDPE (High-Density Polyethylene) | Excellent chemical resistance, high impact strength, low cost | Milk jugs, detergent bottles, automotive parts |
| LDPE (Low-Density Polyethylene) | Flexibility, clarity, low-temperature toughness | Squeeze bottles, packaging films |
| PP (Polypropylene) | High heat resistance, fatigue resistance | Household containers, automotive components |
| PET (Polyethylene Terephthalate) | High clarity, excellent barrier properties, food-safe | Beverage bottles, food containers |
| PVC (Polyvinyl Chloride) | Rigid or flexible, good chemical resistance | Cosmetic bottles, medical containers |
| PC (Polycarbonate) | High impact strength, optical clarity | Water bottles, electronic housings |
| PA (Polyamides/Nylon) | Mechanical strength, abrasion resistance | Technical parts, automotive fuel tanks |
| Others (ABS, SAN, EVOH, etc.) | Specialized properties | Medical, industrial, and specialty packaging |
Material Compatibility Challenges in Blow Molding
Material selection goes beyond mere processability; it encompasses: chemical resistance, product safety, environmental impact, and recyclability. Leshan engineers collaborate closely with raw material suppliers and end-users to address compatibility challenges such as:
- Thermal Stability: Some plastics degrade at high temperatures, affecting machine settings and mold design.
- Barrier Properties: Applications like food and pharmaceuticals require materials that prevent gas, moisture, or odor transmission.
- Mechanical Strength: Products like automotive or industrial containers demand superior impact and tensile strength.
- Regulatory Compliance: Medical and food packaging must meet stringent health and safety standards.
Leshan's Technological Solutions for Diverse Materials
Leshan integrates precise temperature control, advanced screw and barrel designs, and customizable clamping force in their automatic blow molding machines. These features enable seamless processing of polymers with different melting points, viscosities, and flow characteristics. With modular configurations, manufacturers can switch between material types and product forms with minimal downtime.
