Standard mould components
Standard parts for injection moulds
Knarr offer one of the most comprehensive, high quality ranges of standard and special mould components on the market, compatible with industry accepted dimensions in all areas. For example:
- Knarr are considered an expert in ejector pins, blades and sleeves - if we don't have the size you need, we'll make it!
- We have a very extensive range of standard slides and slide holders, rather than designing these yourselves, you can simply adapt an off-the-shelf item.
- Guide pillars, bushes, interlocks, wear/shim plates etc are just some of general standard parts.
- Date stamps, marking units, sprue bushes and air valves are also catalogue items ensuring traceability and accurate mould insert function.
- Allied to the impressive range of parts, Knarr also hold a high level of stock available for immediate delivery to UK or Ireland.
Gunther UK’s offering of KNARR components is backed by sales support, access to CAD data, and integration with broader hot-runner, mould-making and tool-engineering services.
