Prototype Production
Prototype Production

As all manufacturing requirements are reviewed, prototype production begins and customer approvals are received. Any adjustments are made and final programming of parts allows a seamless transition between initial prototype production to high-volume manufacture.
The development of prototypes can also reassure our customers that the end-result will be a quality final product.

Sheet Metal Production
Ongoing Production

Following prototype approval, parts are released for ongoing production and our scheduling and capacity planning systems ensure we can accommodate your demand. Orders are managed by dedicated customer service contacts to ensure the ordering process is hassle-free, and products are delivered on-time, every time.

Metal Manufacturing

Our advanced sheet metal fabrication & precision sheet metal engineering facilities benefit from ISO 9001:2015 Quality Management Certification and some of our specialist manufacturing units also hold additional certifications, including AS9100 for the aerospace and defence industries, ISO 14001 Environmental Management and OHSAS 18001 Health & Safety.

ISO Accredited Fabrication reassures our customers that we have demonstrated the ability to deliver product manufacture and design services that exceed customer (and regulatory) requirements for machine parts.

Welding is a critical process in our operations as precision sheet metal fabricators. Welders at KMF have the substantial experience needed to carry out welding projects of any size or scope for ferrous and non-ferrous materials.

We also hold Welding Approvals to BS EN ISO15614 and Welding Visual Inspection to CSWIP 3.0.

Our precision machining services are currently available to complement any projects required for precision sheet metal customers. KMF can supply machined components in various materials including; carbon/alloy steels, stainless steel, titanium, specialist steel, brass, aluminium and plastics.

KMF offers a full range of metal finishing processes, including powder coating, bead blasting, laser marking and silk screening. Our ability to carry out further processes in house, ensures customer deliveries are not compromised by sub contract operations.

However, if specialist treatments and finishes are required, we have a strong base of approved and trusted suppliers who consistently meet the same high standards for quality, delivery, cost and customer satisfaction as we do.

Precision fabrication, machining, custom metal fabrication and metal finishing isn’t all KMF has to offer. As leading custom sheet metal fabricators we also deliver extensive product assembly services.

We provide manual and automated assembly options, including electrical and mechanical assembly to manufacture sub-assemblies for OEMs who wish to focus on their core competencies. Metal product assembly also includes diligent quality testing, packaging and delivery.

Sheet Metal Solutions

The objective of our Value Analysis & Value Engineering processes is to take your OEM product designs and optimise them for competitive, repeatable manufacture.

We offer rapid prototyping and robust testing and use the latest value engineering software to streamline production, improve quality and deliver long-term cost savings. Our proven systems allow us to move seamlessly from New Product Introduction to repeat order.

Through our industry-leading scheduling software and communication of your demand forecasts and delivery KPIs, we can deliver products exactly to order, on-time.

Lead times range from three days to a typical 10 – 12 days, allowing our customers to match demand to their rate of consumption, without the need to stock inventory. Our flexible processes also mean we can up-scale quickly and perform our sheet metal fabrication and machining as efficiently as possible.

Whether it’s the procurement of supply chain components, or managing free issue parts for assembly, supply chain management is a major part of KMF’s one-stop-shop metal manufacturing service.

With a strong supplier network and a cost-competitive culture, we aim to strengthen your supply chain by building integral relationships; offering expertise on new materials and processes or managing the purchase and supply of additional components for delivery of fully-integrated end products.

When manufacturing large or high-volume fabricated components or assemblies for OEMs, transportation costs can account for a large amount of your overall costs. Whether you use your own transport, use a preferred supplier or rely on KMF's delivery fleet, we will work with you to optimise products and packaging for stable and cost-effective logistics.

With accurate steel fabrication facilities in the UK and Europe (Slovakia), OEMs working across multiple locations can also benefit from multi-site supply to ensure product consistency and quality whilst minimising overall logistic costs.

With 255,000 sq ft of metal manufacturing facilities across the UK and Europe, our capabilities are extensive. We can minimise your risk and lead times by taking care of your OEM products from design to delivery.

Some of our largest, global customers work with multiple businesses across the KMF Group, receiving an outsourced metal manufacturing solution that is optimised for efficiency, speed and quality.

Customers who often outsource to many specialised fabricators, can instead receive an all-encompassing metal fabrication solution from KMF.
