Product Description
10-Cavity Food Grade Aluminum Vacuum Thermoforming Mould for Mirror-Polished Clamshell Lids
Product Overview
This 10-cavity food grade aluminum vacuum thermoforming mould is purpose-built for high-volume production of mirror-polished clamshell lids. Made from premium food-safe aluminum with optical-grade mirror finishing on all cavity surfaces, it delivers uniform, crystal-clear hinged lids with durable living hinges, fully compatible with KIEFEL, ASANO and other high-speed thermoforming lines, ideal for dessert cups, sauce containers and small pastry packaging.
For food packaging manufacturers running premium production lines, our engineering team optimizes multi-cavity vacuum balance, hinge forming precision and machine interface matching, to ensure consistent high-speed forming, uniform transparency across all cavities, and long service life even under continuous cyclic operation.
Engineering Focus
High-quality clamshell lid thermoforming moulds rely on more than just cavity precision. Vacuum uniformity, hinge durability, surface finish and machine compatibility must work together to deliver premium transparent hinged packaging manufacturing.
01
10-Cavity Balanced Vacuum Distribution
Each cavity is designed with surrounding precision vacuum holes with uniform flow resistance, ensuring consistent forming across all 10 cavities, no local thinning or incomplete drawing, and stable wall thickness tolerance of ±0.03mm for every finished lid.
02
Food-Grade Mirror Polished Finish
Grade A optical mirror polishing on all contact surfaces, paired with optimized vent design, eliminates flow marks, haze and silver streaks, achieving over 92% light transmittance, fully compliant with international food contact safety standards.
03
Precision Living Hinge Forming
Targeted process optimization for thin hinge structures, ensuring uniform thinning at the hinge position, resistance to thousands of opening and closing cycles without cracking, while maintaining smooth connection and moderate opening force between lid and base.
04
High-End Machine Precision Matching
Precisely matched to the mounting dimensions, vacuum interface and production rhythm of KIEFEL and ASANO machines, with ±0.02mm positioning accuracy, enabling direct installation and seamless integration with existing high-speed production lines.
