Stronger Metal, Smarter Design
What Is Hot Forging?
Hot forging, also known as hot pressing, is a metal forming process where materials are heated above their recrystallization temperature and shaped using high pressure. This enhances material strength, grain structure, and dimensional accuracy — making it ideal for complex components under mechanical or thermal stress.
At Mattsson Metal, we use vertical and horizontal forging presses to deliver consistent, high-quality parts with tight tolerances and minimal material waste.
Materials We Forge
We specialize in non-ferrous hot forging, working primarily with:
Brass
Corrosion resistance and high machinability
Aluminium
Lightweight and excellent conductivity
Copper
Ideal for components requiring superior electrical or thermal performance
Why Forging Matters More Than Ever
In a world demanding stronger, lighter, and more sustainable solutions, forged components are the hidden heroes. They handle heat. They handle pressure. They last.
Our History
Workshop, casting models and foundry are built. The intended company name was "Sanitary Armatur Gunnar Eriksson".
Gunnar Eriksson invites Oskar Eriksson and Sven Wikstrand. The company is now officially started with the name “AB Mora-Kranar”
The first shipment was delivered to Bröderna Edstrand in Stockholm.
A 125-ton screw press was acquired to initiate the hot pressing of fitting components.
AB Mora-Kranar is sold to FM Mattsson.
The water tap production is phased out and the company will from now on become a pure subcontractor.
The name of the company is changed to FM Mattsson Metal AB.
Mattsson Metal acquires Mora of Sweden's subcontracted part.
The company is expanded with another 950 sqm. The workshop area now consists of 7000sqm.
Ingemar Eriksson, CEO, retires. Replaced by Erik Eriksson.
Mattsson Metal acquires the TKM brand and factory in Kungsör from Uponor.
The company acquires Raufoss Water and Gas (RWG) hot pressing part in Norway.
A major investment project in production worth approximately SEK 40 million is established.
Erik Eriksson (CEO) retires, replaced by Gunnar Genander.
Mattsson Metal invests in a new efficient 400-tonne hot press that replaces several old machines.
Questions About Hot Forging
Detailed insights into the hot forging process, our material choices, and what sets Mattsson Metal apart.
What makes hot forging better for high-strength components?
Hot forging significantly enhances the mechanical properties of a component. By heating metal above its recrystallization temperature, the material becomes more malleable, allowing it to be shaped without internal cracking. The forging process aligns the grain structure with the shape of the part, improving tensile strength, fatigue resistance, and impact durability. This makes hot forging the preferred method for safety-critical parts used in automotive, HVAC, and heavy industry — especially when strength, reliability, and lifespan are non-negotiable.
How does Mattsson Metal ensure precision in forged parts?
At Mattsson Metal, precision is engineered into every step of our process. We design and manufacture all forging tools in-house, allowing full control over dimensions and tolerances. Our automated forging lines — including both vertical and horizontal presses — ensure consistent force and repeatable results. Post-forging, we perform trimming, quality inspections, and, when needed, CNC machining for exact surface finishes and geometries. Every part is produced under ISO 9001 and IATF 16949-certified systems.
What types of components are best suited for hot forging?
Hot forging is ideal for components that need to withstand pressure, motion, heat, or corrosion. Common applications include valve bodies, fittings, connectors, gear blanks, housings, and brackets. These parts are often used in automotive systems, plumbing and HVAC systems, electrical installations, and heavy machinery. Because hot forging enables high material density and structural integrity, the parts perform reliably even in harsh environments.
Can hot forging be used for complex or custom shapes?
Absolutely. One of the major advantages of hot forging is its ability to shape complex geometries that would be difficult or inefficient to machine from solid stock. At Mattsson Metal, we create custom forging dies tailored to each project, enabling us to manufacture near-net shape components that require minimal post-processing. This saves material, reduces weight, and shortens production time — especially valuable in high-volume or technically demanding applications.
What’s the difference between brass, aluminium, and copper forging?
Each material offers unique benefits in hot forging:
Brass: Excellent for components requiring corrosion resistance, durability, and good machinability — widely used in plumbing and fittings.
Aluminium: Lightweight, conductive, and corrosion-resistant — often used in automotive, electronics, and lightweight structures.
Copper: Superior electrical and thermal conductivity — essential for electrical components, power systems, and connectors.
We help customers choose the right alloy for their specific mechanical, thermal, and environmental needs.
What is the typical lead time for a hot forging project?
Lead times depend on the complexity of the part and whether tooling already exists. For repeat orders with existing tools, production can begin within days. For new projects, lead time includes design, toolmaking, sample production, and validation. Our vertically integrated process allows us to accelerate timelines by handling everything in-house, from design to delivery.
Is hot forging environmentally friendly?
Hot forging is one of the more sustainable metal forming methods. It generates minimal waste compared to machining from billet and allows for recycling of nearly all excess material. At Mattsson Metal, we go even further: our production runs on 100% renewable energy, and over 98% of our metal scrap is recycled. We continuously invest in automation and energy-efficient systems to reduce our carbon footprint — making us a strong partner for clients with environmental goals.
What certifications does Mattsson Metal hold?
We are certified according to ISO 9001 (quality management), IATF 16949 (automotive quality), and ISO 14001 (environmental management). These certifications demonstrate our commitment to consistent quality, process control, and sustainability. They also ensure that we meet the high standards expected by global OEMs and Tier 1 suppliers in demanding industries.
