Our products speak for themselves when describing the precision and usability of our multicavity molds

All parts in the mold assembly boast the same exceptional quality with some molds built for use in medical devices incorporating up to 192 individual cavities. Additionally, used mold parts require no adjustments at time of exchange or assembly. This sort of durability makes maintenance easier for the user. Our own production system utilizing our own molds plays a significant role in the supply of speakers and car stereo parts.

Precision Multicavity Molds

The largest mold we have designed and used to date is a 192 cavity mold used in molding parts for medical devices. Many other multicavity molds are produced, such as the 160, 128, 96, 64, 48 and 32.

The first step involved in the production of a multicavity mold is a prototype test mold. It is at this stage that problems such as shape and configuration are solved and a new mold to mass-produce parts is designed.
Long-life Precision Molds

All inserts used in the molds, excluding prototype test molds, are heat-treated and polished to improve durability.

However, in the case of a large number of cavities, even prototype test molds are heat-treated and polished to test-produce sample parts as precise as mass-produced parts.
