What Inoplas Technology does

Inoplas Technology is a UK-based precision plastics contract manufacturer specialising in injection moulding, overmoulding, insert moulding, and cable assembly for OEM customers. Founded in 1973 in Wimborne, Dorset, the company operates a single 25,000 sq ft freehold site housing 26 injection moulding machines with clamp forces from 22 to 180 tonnes, supported by an in-house toolroom, an ISO Class 7 cleanroom, a dedicated ESD-controlled assembly suite, Solidworks CAD with mouldflow simulation, and MSLA/FDM 3D printing for rapid prototyping.

The company serves customers across electric vehicles, medical and biotech, industrial controls, motorsport, and industrial/military sectors, with technical capabilities including liquid crystal polymer overmoulding at 13-micron tolerances, IP69K+ waterproofing, processing of 200+ technical thermoplastics including high-temperature polymers such as PEEK, and ISO 13485-compliant medical device manufacturing. Quality credentials include sustained ISO 9001 registration since the 1980s, ISO 13485, RoHS2, and REACH compliance.

Inoplas operates a B2B, quote-based, project-driven revenue model with multi-year contracts, targeting OEMs from early design through to production. Sales channels are direct (phone, email, website enquiry) supplemented by industry exhibitions such as Interplas and Southern Manufacturing. The company exports globally to Europe, the US, China, Mexico, and Malaysia while maintaining a UK domestic base, and is privately held following a 2001 management buyout by Colin McGhie and Jim Shields.

Products and services

• Injection Moulding Precision injection moulding service with over 50 years of experience manufacturing components, housings, enclosures, and casings using a fleet of machines with clamp forces up to 180 tonnes and shot capacities from 0.5 to 380 grams. Includes technical injection moulding, two-shot moulding, and low-pressure moulding for OEM customers.
• Overmoulding Overmoulding service that adds a second layer of plastic to existing components to enhance performance, aesthetics, and functionality. Specialises in overmoulding cables, inserts, PCBs, and electronic components, achieving tolerances as small as 13 microns and IP ratings up to IP69K+.
• Insert Moulding Insert overmoulding service where inserts (typically metallic but also plastic or wood) are placed into the moulding machine and plastic is injected around them to create a durable mechanical bond, reducing post-moulding operations and production time.
• Cable Assembly
