Our Capabilities

Technical Expertise

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

We are constantly investing in the latest technologies, such as high speed stamping, to give your products the edge in an increasingly competitive world.

For detailed explanations of our manufacturing capabilities, use the menu above.

Moulding

CAD/CAM and CNC equipment enable 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.

Injection Moulding

Our Arburg injection moulding machines have the ability to mould most thermoplastic materials, up to a shot weight of 75 grams. Assembly operations such as inserting, printing and over-moulds, together with other assembly processes, can also be carried out within the moulding department.

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 regularly with toolmakers and design engineers to ensure the complete production cell operates to the best possible efficiency.

Press Machinery at Harwin:

• 18 tonne - max speed 1000 strokes per minute
• 25 tonne - max speed 1400 strokes per minute
• 20 tonne - max speed 2000 strokes per minute with PC-based 'B' control

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 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, aluminium, brass, mild steel, plastic, titanium and copper.

Machinery includes:

• 5 x Star SB-16
• 2 x Star SB-16E
• 4 x Star SR105
• 1 x Star SR20R11

Electroplating

In line with the company's policy of vertical integration, Harwin has designed and built several high speed plating lines. 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.

• Reel Plating lines
• Selective Plating lines

Tooling

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 manufacturing our own mould tools, press tools and assembly equipment, 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 optimised levels ensuring efficiency and reliability over the life of the product being produced.

Machinery includes:

• Agie and Charmille wiring machines
• Agie and Sparkatron spark erosion machines
• Sodik E.D.M. hole drillers
• Jones and Shipman camera-assisted grinding machines

Assembly & Packaging

No matter how simple or complex the requirement, Harwin has the in-house capability to assemble and package your component orders competently and on time.

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.

Quality

Harwin's commitment to quality extends to all areas of the organisation, from Executive Management through to Production.

Our Quality Policy is based on the following principles

• The training of all employees in the disciplines of our ISO 9001 Quality System.
• Commitment to Continuous Improvement of Products and Services, via the use of an effective Preventive and Corrective Action System.
• An open computer system of real-time information, to encourage employee participation and feedback on all matters relating to the effective running of the company.
• A positive and helpful attitude from all employees at all times, which translates into a personal, responsive and highly professional service for our customers.

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
• DESC #06EX9 (CAGE Code #K0536).

Harwin's commitment to quality

• 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).
