Broanmain Plastics is a specialist technical precision component manufacturer supplying OEMs in the medical, scientific, FMCG, electronic, automotive, aerospace and defence sectors. 


Broanmain Plastics, founded over 60 years ago, is a specialist technical precision component manufacturer supplying OEMs in the medical, scientific, FMCG, electronic, automotive, aerospace and defence sectors.

 From high volume production runs to precision moulding, CNC finishing and assembly, we are one of the few UK plastic specialists to offer all of the design, moulding and setting techniques, prototype development and distribution services through one facility. Fully project managed by technically competent industry, materials and application experts.

To help eliminate manufacturing headaches, meet tight delivery schedules and maintain product quality, we provide upfront quotes to:

  • Manage the complete project, including all investigative material research, prototyping, coordination with specialist designers and toolmakers, right through to tool sign off and shipment
  • Deliver full scale production, from small technical batch work to high-volume precision moulding, including larger parts requiring high strength and uniformity
  • Repair and rapid development of prototype mould tools, using materials ranging from polymer to copper, aluminium and other metals
  • Complete robust Quality Assurance trials
  • Maintain and service tools
  • Undertake precision CNC milling and parts customisation
  • Post-moulding milling, finishing and assembly services
  • Enhance print aesthetics, including RFI electronic device shielding, pad printing, chrome or coloured protective plating, serial laser marking, etc.

We mould intricate polymer parts ranging from 0.1mm in size right up to shot weights of up to 3kg, including an extensive range of electronic housings,connectors, gears, micro-switches and industrial technical components

 “Being able to partner with a likeminded moulder that shares our engineering flair is important for both innovation and continuity. Right from the outset Broanmain has gone the extra mile. As well as helping us with the tooling design, we leaned on the team a lot for guidance on processing, tooling development and materials.” Anthony Gomme, Strategic Buyer, Specac Ltd.

Broanmain offers a full suite of precision post-moulding milling and part customisations.


Sustainable stock management

COVID-19 has exposed our global vulnerabilities and interdependencies, which will likely shift supply chain dynamics again. If like many OEMs you are re-evaluating supply chain options, talk to us about our stock management systems and how these can help you to reduce lead-times, avoid the need to estimate order sizes and smooth out peaks and troughs in sales.

Choose from:

  • Just in Time (JIT)
  • Kanban call – off
  • Vendor Managed Inventory (VMI)
  • Discrete Order
  • Electronic Data Interchange (EDI)
  • Line Side Deliveries (local businesses only)

As part of our sustainability commitment, we optimise box capacity, use Kanban to eliminate over production and now offer a new recycling box collection service to local customers

Delivering customer value

Whatever your application or budget, Broanmain’s flexible assembly services guarantees the highest quality. Ranging from:

  • Two-part assembly to a complex string of sub-assemblies to full assembly of multiple components
  • Ultra-sonic welding to reliably join plastic parts together without using connective bolts, screws or fastenings
  • Reaming and tapping to create bespoke micro-precision holes and threads


Our experienced team offers a range of high-quality assembly options to suit your project and budget


Broanmain has managed well over 200 bespoke tooling projects, from concept to validation




Products and Services




Our Manumold and Sumitomo (SHI) Demag plastic injection moulding machines range from 25 to 550 tons with shot weight capacity up to 3500 grams. Our machines are equipped with mould tool heating, colour dosing, conveyors and material drying facilities, installed for all polymers. Giving us the capacity to mould micro precision components alongside larger parts. We recently invested in an energy efficient all-electric IntElect moulding machine.



Hurco VM10i, with 10K RPM spindle and full Renishaw probing system (660 x 406 X 508 mm)

Achieves complex and repeatable 3D and 2D geometries and delivers better surface finishes on the most intricate of parts. Accuracy is further enhanced with the assistance of Renishaw’s TS27R tool setter and OMP400 part probe.



Semco LC 1 1/2 VS (760x 300x 400 mm)

Used for quick projects like drilling and facing


XYZ SLX 1630 (400 x 760 mm), 56mm through bore, 2.5K RPM

CNC lathe used for turning complex individual parts and small batches.


Harrison VS330TR (330 x 635 mm), with 3K RPM

Manual lathe used for simple cylindrical parts and individual bespoke parts.


Jones and Shipman 540 P (480x 170x 250mm), with Optidress

Used to grind very precise and flat surfaces +/- 0.005mm. With addition of Optidress wheel-forming attachment Broanmain can grind radiuses, angles and more complex shapes into work pieces.



Joemars 322 sinker EDM (600x 300x 400mm), with Erowa pallet system

To make precise burns in any conductive material, regardless of hardness. Used to machine shapes and forms into materials that can’t be accomplished using a manual or CNC milling machine, e.g. modifying features on an existing tool that has already hardened through electro-discharge machining.



Baty R14 profile projector, with 10x magnification

Very handy for measuring small through features such as slots and ribs


Aberlink Xtreme 500 CNC CMM

Coordinate measuring machine used to inspect complex geometry.

Renishaw OMP400

Accurate probe coordinate measurements.

Range of manual measuring equipment
Portable hardness tester
Granite surface plate (900 x 600 mm)

Measuring equipment for producing accurate and repeatable products that comply with customer requirements.



Fusion 360, with CAD/CAM
Solidworks 2019 + HSMworks, with CAD/CAM

Giving Broanmain complete control of the component design using 3D software to create digital drawings and then reproduce complex 3D contours repeatedly on technical components
