Filling Balance
Thin-wall parts need fast and even filling. Gate position, runner size, venting and flow path are reviewed to reduce short shots, burn marks and uneven packing.
Thin-Wall Injection Mold
Thin-wall plastic product tooling designed for efficient cycle time, balanced filling and stable production.
Overview
Thin-wall injection molds are built for plastic parts that need fast filling, short cycle time and stable dimensions. The challenge is not only making the shape, but controlling flow balance, cooling efficiency and ejection without deformation.
Shengqi reviews wall thickness, material flow length, gate position, part stiffness, cavity quantity and injection machine requirements before confirming the mold plan.
For high-volume thin-wall products, tooling quality directly affects cycle time, scrap rate and long-term production stability. Mold design and trial molding feedback are both important before approval.
Engineering Focus Areas
Cooling Efficiency
Cooling layout affects cycle time and part deformation. The mold plan considers cooling channels, part thickness distribution and areas that may trap heat.
Ejection Reliability
Thin-wall products can deform during ejection. Ejector position, release angle, polishing and product ribs are reviewed to support stable part removal.
Production Cycle Planning
Cavity quantity, mold steel, hot runner or cold runner choice and machine tonnage are discussed according to the customer's target quantity and budget.
Quote Requirements
- 3D drawing or product sample photos with dimensions
- Plastic material, wall thickness and target part weight
- Expected cavity number or annual production quantity
- Injection machine tonnage if already selected
- Surface, stacking, sealing or assembly requirements
