(C) Thermoforming: Thin-Wall Lightweight Production

Process Advantages:

Minimum wall thickness 0.3mm, 40% lighter than injection molding, material utilization ≥95%.

Rapid prototyping for small batches (1–1,000 pieces), mold cost 60% lower than injection molding.

Key Parameters:

Heating temperature 180–240°C, forming pressure 0.5–1.0MPa, suitable for PS/PE materials.

Dimension accuracy ±0.5mm, ideal for thin-wall products like disposable meal boxes and storage baskets.

(D) 3D Printing: Custom Prototyping & Rapid Sampling

Technical Features:

Supports complex curves (streamlined handles, hollow patterns), minimum detail size 0.5mm.

Options for photosensitive resin (accuracy ±0.1mm) and PLA eco-material (biodegradation rate ≥90%).

Application Scenarios:

Custom bathroom fixtures (unique towel racks), DIY gardening tool accessories (accuracy ±0.2mm).
