Bolster and Insert Plate System for Injection Moulding

Bolster and Insert Plates for Injection Moulding

At Protoshape, we specialise in bolster and insert plate systems for injection moulding, offering fast, flexible, and cost-effective tooling solutions. Based in Linlithgow, Scotland, perfectly positioned between Edinburgh and Glasgow, we serve customers across Scotland and the UK with high-quality tools capable of producing hundreds of thousands of parts.

Whether you’re prototyping, running low-volume production, or producing mid-volume batches, our bespoke tooling systems deliver precision, speed, and cost savings that full steel tools aren’t always necessary to achieve.

Bolster Plates – Cost-Effective High Performance Tooling

Our bolster plate system is designed to streamline production while maintaining excellent part quality:

Simplified tooling: only the two cavity plates and ejection are required, no need for a full mould
Fast and efficient: shorter lead times compared to conventional steel moulds
Durable and productive: capable of producing up to 100,000 parts with proper maintenance
Material flexibility: supports commodity plastics like PP and HDPE, engineering plastics such as ABS and Nylon, as well as recycled and biodegradable plastics

Bolster plates are ideal for:

Rapid prototyping – test designs quickly with minimal tooling cost
Pilot production runs – get functional parts ready for market testing
Low to mid-volume production – high-quality, cost-effective solutions without the expense of a full steel tool

Insert Plates – Fastest, Most Flexible Solution for Low Volumes

For smaller quantities, our insert plate system provides unmatched speed and efficiency:

No ejection required, simplifying setup and production
Only two plates slot into our bespoke tool, allowing even faster production
Lower cost than bolster plates, ideal for small runs
Capable of producing short-run prototypes, limited edition parts, or test components

Insert plates are perfect when you need:

Rapid iteration – produce multiple design variations quickly
Cost-conscious production – avoid the high upfront cost of full moulds
Reliable part quality – even for very low volumes, precision is maintained
