Description

The mold is engineered for the efficient production of L-size labor protection respirator mask parts, with a focus on ergonomic fit, dimensional stability, and long-lasting durability. By applying a hot runner system, it achieves reduced material waste and uniform flow distribution, making it ideal for protective equipment manufacturing where both precision and efficiency are critical.
In combination with liquid silicone overmolding processes, this mold ensures seamless bonding of PA inserts with silicone layers, providing strong sealing, comfort, and reliable integration for half-mask respirators.

Mold Design & Key Technologies

Hot Runner System for Stability
The hot runner system ensures uniform material flow, reduced waste, and stable injection performance across production cycles.

Single-Cavity Precision Design
The single-cavity layout provides dimensional accuracy, especially suited for large mask overmolding accessories where consistency is essential.

Optimized Gating and Venting
Careful gating placement and venting channels prevent short shots, air traps, and flashing, ensuring smooth cavity filling.

High-Accuracy Manufacturing
Advanced CNC and EDM machining guarantee tight tolerances, smooth cavity surfaces, and reliable overmolding performance.

Ergonomic Fit and Structural Integrity
The cavity design is optimized to meet ergonomic requirements of labor protection masks, ensuring comfort and secure sealing.

Flexible Productivity Enhancement
Although currently designed without automation, the mold can be combined with a double-lower-mold system to improve cycle efficiency and reduce downtime.

FAQ

Q1: What distinguishes the L-size mold from the M-size version?
A1: The L-size mold produces larger mask accessories, while maintaining the same precision and ergonomic standards.

Q2: Can the mold design be customized?
A2: Yes, cavity structure, parting line, and surface finishing can be tailored to meet specific requirements.

Q3: Is automation available for this mold?
A3: The mold itself is designed as a single-cavity system, but it can be adapted with a double-lower-mold setup to increase productivity.
