What is Metalworking?
Fundamentals, Industries, and Industrial Significance
LMV BLOG – Lauingen 2026-06-01
Metalworking is one of the fundamental disciplines of modern industry and, at the same time, a term that encompasses a broad spectrum of technologies, industries, and value chains. Anyone who procures, plans, or purchases metal parts should understand what metalworking means in an industrial context, which areas it covers, and what demands it places on manufacturers and suppliers.
This article explains the basic principle of metalworking, highlights its economic importance, and provides an overview of the industries and application areas where it is indispensable.
1. Key Facts at a Glance
-
Metalworking encompasses all processes by which metallic raw materials are transformed into technically usable components and products
-
It is divided into primary processing (smelting and foundry technology) and secondary processing (forming, separating, joining, coating)
-
Key customer industries: mechanical engineering, automotive industry, construction industry, furniture industry, medical technology
- Metalworking is a central part of German industry, with over 90,000 companies in the manufacturing sector alone
- Quality, material selection, and process chain are decisive factors for the cost, function, and lifespan of a component
2. The Definition of Metalworking
Metalworking refers to the industrial and artisanal process in which metallic materials, including steel, aluminum, stainless steel, copper, or brass, are transformed into components, semi-finished products, or finished products through various procedures.
The term is deliberately broad: it includes both large-scale industrial steel processing and single-part production in contract manufacturing. Crucially, a metallic material is brought into a defined shape or state through targeted mechanical, thermal, or chemical action.
From raw form to component, a metal part typically undergoes several process stages that must be coordinated with each other.
3. Primary and Secondary Processing: How Metal is Created and Shaped
Primary Processing
Primary processing begins with the extraction and preparation of metal ores, followed by smelting. This produces raw metals and semi-finished products such as sheets, rods, profiles, and tubes – the starting materials for all subsequent processes.
Secondary Processing
Secondary processing involves the actual machining and processing of these semi-finished products into functional components. It can be divided into four main categories:
Forming – changing the shape without material removal (e.g., bending, rolling, deep drawing)
Separating – material removal through mechanical or thermal processes (e.g., sawing, punching, laser cutting, grinding)
Joining – connecting individual parts to assemblies (e.g., welding, soldering, screwing)
Coating – applying surface layers for protection or finishing (e.g., galvanizing, powder coating, chrome plating)
These four categories should not be viewed in isolation. In practice, they are combined in defined process chains – depending on the material, component geometry, tolerance requirements, and intended use.
4. Materials in Metalworking
Material selection is one of the essential decisions in component development. The most important material groups:
Steel and stainless steel are the most commonly processed metals in industry. Steel impresses with high strength and good workability; stainless steel with corrosion resistance and suitability for hygienic applications.
Aluminum is lightweight, corrosion-resistant, and easily formable – primarily used in automotive engineering, mechanical engineering, and aerospace.
Copper and copper alloys (brass, bronze) play a role primarily in electrical engineering and sanitary applications.
Special materials such as titanium or nickel-based alloys are used in demanding environments, for example, in medical technology or the chemical industry.
The choice of material directly influences which processing methods are technically sensible and economically viable.

5. Application Areas: Where Metalworking is Indispensable
Metalworking is the basis of almost all industrial value chains. The most important customer industries:
Mechanical engineering – housings, frames, shafts, brackets, precision parts for machines and systems of all kinds
Automotive industry and vehicle technology – body parts, chassis components, drivetrain, add-on parts
Construction industry and metal construction – supporting structures, facade elements, stairs, railings, fasteners
Furniture industry and interior design – furniture frames, fittings, shopfitting systems, metal design elements
Medical technology – implants, instruments, device housings with the highest demands on purity and tolerance
Electrical engineering and electronics – housings, heat sinks, contact parts, cables
Aerospace – high-precision components made from special materials under extreme stress requirements
6. Quality Requirements and Standardization
Metalworking in an industrial context is bound by norms and quality standards. Relevant frameworks include:
- DIN and EN standards for materials, tolerances, and processes
- ISO 9001 as the basis for quality management systems
- Industry-specific standards such as IATF 16949 in the automotive industry or EN ISO 3834 in welding
- Material certificates (e.g., EN 10204) as proof of material composition and test results
For purchasing companies, this means: a qualified metalworking company documents not only its results but also its processes – from incoming goods inspection to final control.
7. Metalworking at LMV: A Single-Source Process Chain
LMV Lauingen is a specialized metalworking company with many years of experience in processing demanding steel components. The service portfolio covers the entire secondary processing: bending, grinding, welding, machining and punching, tube laser cutting, as well as galvanizing, chrome plating, and powder coating.
On the product side, this results in concrete system solutions: furniture components, shopfitting systems, and industry-specific solutions for various customer markets.
What this means in practice: components go through several process stages under one roof. This reduces interfaces, shortens supply chains, and ensures consistent quality across all manufacturing steps, from the initial forming to the finished surface.
8. Current Developments in Metalworking
The industry is undergoing structural change. Three developments particularly characterize the present:
Automation and Digitalization: CNC machining, robot-assisted welding processes, and digital production control increase precision and reproducibility. At the same time, dependence on manual individual processes decreases.
Sustainability and Circular Economy: Metallic materials are fundamentally fully recyclable. Energy efficiency in processing and the use of secondary raw materials are gaining economic and regulatory importance.
Individualization with simultaneously increasing cost pressure: Lot size 1 is technically possible but economically challenging. Flexible manufacturing systems and close coordination between design and production become a competitive advantage.
9. Frequently Asked Questions about Metalworking
1. What is the difference between metalworking and manufacturing technology?
Manufacturing technology describes the specific processes and their technical execution (e.g., turning, milling, welding). Metalworking is the overarching term that encompasses the entire process from material to product, including material selection, process chain, and quality assurance.
2. How important is quality assurance in metalworking?
Compliance with standards (DIN, EN, ISO), material certificates, and documented testing processes are standard in the industrial supply chain and often a prerequisite for supplier qualification.
3. What role does sustainability play in metalworking?
Metallic materials are fundamentally fully recyclable. Energy efficiency in processing and the use of secondary raw materials are gaining both economic and regulatory importance.
4. What does lot size 1 mean in metalworking?
Lot size 1 refers to single-part production – i.e., the manufacture of a component without series quantity. This is technically possible through CNC machining and flexible manufacturing systems but places high demands on economic efficiency and process planning.
