Half Mask Respirator is also called silicone half mask, silicone respirator, silicone face mask, silicone rubber mask, made of medical grade silicone rubber material and can be molded by LSR injection molding/LIM or compression molding, the difference exists in development cost, production capacity, product quality, etc.

How to choose a suitable molding for your silicone respirator mask?

Half Mask Respirator made by Liquid Injection Molding (LIM) VS. Compression Molding:

Half mask mold cost is different:

LIM mold cost for half mask is much higher than compression mold for half mask - for half mask requires more mold templates such as clamping plate, piston plate, manifold, insulation plates, spacer block, ejector clamping plate, ejector bottom plate, bottom clamping plate, not similar to compression mold that just need upper plate, mold cores, and lower plate that mold structure is simpler.

Compression Molding for Half Mask

Half mask unit cost is different:

Unit cost is depend on production capacity and efficiency, half mask unit price made by LIM is cheaper than compression molding.

Regarding LIM mold, for saving unit cost, generally use double-mould injection molding, 6 cavities for one mould. High-Automation Manufacturing extremely increases production capacity so that decrease unit price.

Half Mask quality is relatively different: it is well known that LSR injection molding can manufacture high precision silicone rubber products with very small parting line, and nearly without burrs, which means LIM is more suitable for strictly quality management requirements. If with high purchase volume and quality requirement, LSR injection molding is better choice than compression molding.
