INJECTION MOLDING SERVICES
AAA MOULD provides customized injection molding services, covering the entire production process from material selection, mold design and manufacturing to final injection-molded products. We are ready to tackle the challenges of various types of injection-molded parts, such as strict tolerances, thin walls, small draft angles, undercuts, complex part geometries, defect-free surface finishes, etc. These services include multiple product types:
The advantages of injection molding include
The more injection-molded parts produced, the lower the unit cost. This is because the largest expense is creating the metal mold—once the mold exists, simply filling it with plastic is relatively inexpensive.
Common Injection Molding Materials
Materials used in injection molding can be divided into four categories: thermoplastics (the most common), thermosets, elastomers, and composites. Below are some of the more common materials:
General-Purpose Plastics (High Production Volume, Wide Application, Low Cost)
◦ Properties: Chemical resistance, high rigidity, low-temperature resistance
◦ Applications: Containers (e.g., laundry detergent bottles), pipes, bottle caps
• Low-Density Polyethylene (LDPE)
◦ Properties: Soft, transparent, good impact resistance
◦ Applications: Plastic bags, cling film, flexible hoses
• Polypropylene (PP)
◦ Properties: Bend-resistant (microwave-safe), oil resistance
◦ Applications: Tableware, automotive components, fibers (e.g., non-woven fabric)
• Polystyrene (PS)
◦ Properties: Transparent, rigid and brittle, easy to process
◦ Applications: Disposable tableware, toys, foam plastics (e.g., EPS)
◦ Properties: Balanced comprehensive performance (high strength, impact resistance, easy coloring)
◦ Applications: Household appliance casings (e.g., TVs, washing machines), automotive interiors, 3D printing
• Polystyrene + Polyphenylene Ether (PS-PPE)
◦ Properties: High-temperature resistance, flame retardancy, dimensional stability
◦ Applications: Electronic and electrical components, automotive parts
Engineering Plastics (High Performance, for Structural or Functional Components)
• Nylon 66 (PA66)
Properties: High strength, wear resistance, oil resistance, chemical corrosion resistance Applications: Gears, bearings, automotive components, textile fibers
• Glass-Filled Polyamide (PA-GF)
Properties: Enhanced rigidity and heat resistance based on PA (filled with glass fibers) Applications: High-strength structural components (e.g., parts around the engine)
Properties: Fatigue resistance, good weatherability, excellent electrical insulation Applications: Electronic connectors, automotive bumpers, home appliance components
• Polyethylene Terephthalate (PET)
Properties: Transparency, tensile resistance, chemical corrosion resistance
Applications: Beverage bottles (e.g., mineral water bottles), films, fibers (polyester)
Properties: High transparency, extremely strong impact resistance (raw material for bulletproof glass), high temperature resistance
Applications: Optical lenses, electronic device casings, automotive lamp covers
• Glass-Filled Polycarbonate (PC-GF)
Properties: Improved rigidity and dimensional stability based on PC (filled with glass fibers)
Applications: High-precision mechanical parts, automotive structural components
• ABS Polycarbonate (PC-ABS)
Properties: An alloy of PC and ABS, combining high impact resistance and processability
Applications: High-end home appliance casings, automotive dashboards
Properties: Excellent optical transparency (light transmittance over 90%), good weatherability Applications: Optical lenses, signage, bathroom fixtures, aircraft canopies
