When completing CNC custom processing parts and starting assembly, plastic components are often needed. The most common materials used are TPU (Thermoplastic Polyurethane) and silicone. These two materials have distinct characteristics, and the choice can be made based on specific requirements.
1. Material Properties
TPU (Thermoplastic Polyurethane)
- Elasticity and Abrasion Resistance: TPU exhibits excellent elasticity and abrasion resistance, maintaining its shape and performance through repeated use.
- Processability: TPU is easy to process, making it suitable for CNC technology to manufacture complex-shaped components.
- Temperature Resistance: TPU retains stable physical properties at higher temperatures, suitable for various application environments.
Silicone
- Flexibility and Temperature Resistance: Silicone has extremely high flexibility and can be used in a temperature range of -50°C to +230°C, making it highly adaptable.
- Chemical Stability: It has excellent resistance to various chemicals, commonly used in medical and food-contact applications.
- Electrical Insulation: Silicone is a good electrical insulator, suitable for electrical components.
2. Application Fields
TPU
- Commonly used in automotive, electronic products, and sports equipment, TPU provides good protection and comfort due to its abrasion resistance and elasticity.
- Suitable for manufacturing seals, gaskets, and soft casings.
Silicone
- Widely used in medical devices, kitchen utensils, and baby products, silicone is favored for its safety and high-temperature resistance.
- Commonly used for making waterproof seals, molds, and various flexible components.
3. Cost and Production Efficiency
TPU
- High processing efficiency, suitable for mass production, and overall costs are relatively low.
- CNC processing is flexible, allowing for easy design modifications and quick market response.
Silicone
- Production cycles are longer, especially for complex-shaped products, leading to relatively high mold costs.
- Although the initial investment is higher, its durability may lead to lower long-term costs.
4. Conclusion
When choosing between TPU and silicone as materials, it is essential to consider the specific application requirements comprehensively. TPU is suitable for scenarios that require high elasticity and abrasion resistance, while silicone is more appropriate for applications needing high-temperature resistance and chemical stability. Effectively utilizing the characteristics of these two materials can provide optimal solutions for CNC custom processing parts, meeting various customer needs.
