Introduction

The customization of injection plastic products involves several critical stages, from selecting the appropriate materials to designing the mold and adding finishing touches. This article delves into these processes, highlighting specific parameters for each stage and Dongguan Longying company's unique solutions.

Materials Selection

Material selection is foundational. Factors include tensile strength, impact resistance, thermal stability, and cost.

• Common materials: Polypropylene, Polyethylene, ABS, and Polystyrene.
• Specific parameters: Tensile strength (25-50 MPa), impact resistance (10-30 kJ/m²).

Mold Design and Engineering

Mold design is crucial for precision and efficiency. CAD software and simulation tools are used to design molds that can produce parts within specific tolerances (±0.1 mm).

Color and Finish Customization

Customizing the color and finish involves pigmentation and surface treatment techniques.

• Color matching with standardized color codes such as Pantone.
• Finishes: Glossy, matte, textured.

Part Design and Functionality

The design phase ensures that the part meets functional requirements while optimizing material use.

• Wall thickness: Typically between 1-4 mm to ensure structural integrity.
• Draft angles: 1-2 degrees for easy release from molds.

Dongguan Longying Company Solutions

Dongguan Longying offers comprehensive customization services, delivering high precision and quality.

• Precision molding with tolerances as tight as ±0.01 mm.
• Advanced material blends for enhanced performance.

Post-Processing Options

These include painting, coating, and assembly to finalize the product.

• Painting: Electrostatic and spray painting.
• Coating: UV resistant, anti-scratch coatings.

Quality Assurance and Testing

Quality assurance involves rigorous testing to meet industry standards.

• Tests include tensile testing, impact analysis, and thermal cycling.
• Compliance with ISO 9001 standards.

Cost Considerations

Cost is influenced by material choice, mold complexity, and post-processing.

• Initial mold cost: $5,000-$50,000 depending on complexity.
• Per unit cost reduction with higher volumes.

Environmental Impact

Environmental considerations include material recyclability and energy efficiency.

• Recyclable materials: PET, HDPE.
• Energy-efficient practices: Use of electric injection molding machines.

Conclusion

Customization of injection plastic products is a multifaceted process that offers numerous opportunities for innovation and optimization. By understanding each stage's specific parameters, companies can achieve high precision and functionality in their products.
