Harwin - An Overview
Harwin's capabilities have developed in response to the specialist interconnection demands of OEM electronics manufacturers and Harwin's philosophy of building for the future. With a policy of investing 10% of turnover year on year and replacing equipment on a five year cycle Harwin is able to keep up with the rate of change in technologically advanced machines.
We offer a total in-house design and manufacturing service from initial consultancy, evaluation and prototyping, through to tooling, electroplating, stamping, moulding, precision turning, auto-assembly and packaging.
Harwin can meet virtually any interconnection challenge through:
- Our extensive range of standard connectors and components, including ultra-fine 0.5mm pitch to 2.5mm pitch PCB connectors and plastic and metal hardware.
- Application-specific connectors, custom-designed/adapted and manufactured to meet the most precise specifications and project demands
- Total solutions for the world's most demanding markets including military and aerospace, automotive, consumer electronics, telecoms, medical, test and measurement, and more
Design/Technical
Harwin's technical expertise and total in-house manufacturing capability enable us to provide the highest quality products and allow us to respond to customer's individual needs quickly and efficiently.
Commitment to manufacturing
In an industry that is fast changing and constantly evolving, Harwin recognises the importance of Research & Development. By investing in new technology and skills, we are able to respond to customer's individual needs quickly and efficiently.

Engineering
Harwin have an unchanging belief in the total control of all the research, design and development of all tooling used within our manufacturing processes.
By developing our own mould tools, press tools and assembly equipment using the latest CAD software, not only can we supply dedicated tooling for your applications at an appropriate scale, we also retain total control over project lead times and costs. All tooling is designed to run at optimized levels ensuring efficiency and reliability over the life of the product being produced.
Machinery includes:
- Agie and Charmille machines- down to 70 micron wire
- Agie Hyperspark - 28 position tool change
- Agie EDM hole driller
- Agie and Charmille CNC EDM fully automated
- Jones and Shipman camera-assisted grinding machines
- Micron VCE 800 - Milling machine- vertical machining centre
- GraphiteMaster MoldMaster HSM Fully automated machine
Moulding
CAD/CAM and CNC equipment enables us to build quality mould tools for high performance production with interchangeable, close tolerance components, whether from single or multiple cavities.
Our team of designers, toolmakers and process engineers work closely together to ensure a smooth transition from design and FMEA via mould tool manufacture to process-capable production
Machinery includes:
- 25, 50 & 80 tonne- injection moulding up to a shot weight of 150 grams
- Rotary insert moulding machines
Stamping
To support a growing demand for precision metal stampings, Harwin has substantially enhanced the capacity of its stamping facilities by investing in high-speed Bruderer presses.
Highly trained Press setter/operators regularly inspect both production parts and tools and liaise constantly with toolmakers and design engineers to ensure the complete production cell operates to the best possible efficiency.
Machinery includes:
- 25 tonne - max speed 1400 strokes per minute
- 20 tonne - max speed 2000 strokes per minute with PC-based 'B' control
- 20 tonne long bed servo assisted feeder - 2000 strokes per minute
Turning
Since its formation more than 50 years ago, Harwin has specialized in the manufacture of precision turned parts for the electronics industry and has a wealth of experience in this area.
Harwin employs the latest polar co-ordinate milling CNC technology to produce highly complex components in a single operation. We have the capacity to manufacture turned parts of diameters between 0.5mm and 20mm, and up to 300mm in length, in a variety of materials including: stainless steel, aluminum, brass, mild steel, plastic, titanium and copper.
Machinery includes:
- Star SB-16, 2—16mm diameter bar
- Star SB-16E, 2—16mm diameter bar
- Star SR105, 2—10mm diameter bar
- Star SR20R11, 3—20mm diameter bar
Electroplating
In line with the company's policy of vertical integration, Harwin designs and builds our own plating lines in order to keep pace with changing plating technology and environmental requirements. This highly efficient plating facility is an integral part of the company's manufacturing unit. In order to keep pace with increased production a substantial investment in the plating process has taken place over the last few years.
Developments within the plating facility have allowed for a number of innovative techniques to be adopted to improve the selective plating process, making it possible to achieve accuracy of the plating position to 0.2mm and better. Chemical control can now be achieved by the use of X-ray fluorescence for solution analysis giving greater accuracy and faster results. Other quality assurance methods used include atomic absorption, artificial ageing and solderability testing. These methods, together with micro section facilities, ensure optimum plating conditions that guarantee your electro-plating specifications.

- Barrel Electro Plating lines
- Reel Plating lines
- Selective Plating lines
Machinery includes:
- Artificial ageing machine
- Spetra atomic absorption machine
Assembly
No matter how simple or complex the requirement, Harwin has the in-house capability to assemble and package your requirements. Harwin manufactured assembly machines and in process visual inspection ensure short lead times and the highest levels of quality.
Using our in-house designed assembly and packaging machines, your requirements for special marking, testing or packaging can be easily incorporated into the component manufacturing process.
Harwin's commitment to quality
- Harwin's commitment to quality extends to all areas of the organisation, from Executive Management through to Production.
- Product design, tooling and Harwin-built automatic assembly machines are subject to Failure Modes and Effects Analysis (FMEA), Design for Assembly (DFA) and other strict, quality control procedures prior to production.
- Statistical Process Control (SPC) techniques monitor the production process. Our goal is Sigma 6 (zero defects).
Quality approvals
- BS EN ISO 9001:2000. While many other manufacturers wait for approval, Harwin's 50-plus years of commitment to quality has helped us to earn the coveted ISO 9001 Certification.
- IECQ-CECC (Datamate Product Range) certificate number: M1016 IECQ-CECC
- BS9000: Certificate No. 2538/F Registration No.:1243/M
