Deep-drawn parts Manufacturers online

Deep-drawn parts are shaped workpieces that are produced from flat sheet metal or plastic film by deep-drawing - a forming process - whereby the material is drawn into a mold to create complex hollow bodies.

They are used for packaging, car body parts or technical housings, for example, and are characterized by high dimensional accuracy and material utilization.

Below you will find an overview of the production process, an overview of the use of deep-drawn parts and their advantages:

Procedure of the deep-drawing process:

Deep drawing is particularly suitable for materials such as steel, stainless steel, aluminum and brass, but also plastic foils, as these materials have good ductility (formability).
The deep-drawing process is a type of cold forming in which a flat sheet or plastic film is formed into a three-dimensional shape.

The process comprises the following steps:

1. A flat sheet of the material to be processed is cut to size and cleaned to remove impurities.
2. The material is heated to a certain temperature to make it softer and more malleable. This step makes it easier to draw the material into the desired shape.
3. The heated material is placed on the mold plate or core, which has the desired shape of the final product.
4. A punch is used to press the material into the mold. The sheet or foil is drawn around the mold and takes on its contours. This step can be repeated several times to achieve the desired depth and shape.
5. After the deep-drawing process, excess material and burrs are removed. If necessary, additional processing steps such as drilling, cutting or grinding can be carried out to finish the part.

Use of deep-drawn parts:

Deep-drawn parts are used in numerous industries and application areas. They are used when components with high strength, complex geometry and a smooth surface are required. Typical areas of use include:

1. Automotive industry:
Deep-drawn parts can be found in car bodies, engine parts, exhaust systems and fuel tanks. They provide the necessary stability, lightness and corrosion resistance for long-lasting components.

2. Household appliances:
Deep-drawn parts are used in washing machines, refrigerators, microwaves and dishwashers, for example as drums, housings, cladding and inner door panels.

3. Electrical engineering:
Deep-drawn housings for electrical components such as switches, sockets and connections are often made of stainless steel or aluminum, as they provide reliable shielding and protection against external influences.

4. Medical technology:
Medical technology uses deep-drawn parts for sterile instrument housings, surgical tools and parts of medical devices. Smooth surfaces, high precision and stability are particularly important here.

5. Packaging industry:
Deep drawing is used in the production of food or cosmetic packaging, especially for cans and tubes, as it enables fast and cost-effective production.

6. Aerospace:
In the aerospace industry, deep-drawn parts are used for structural components, cladding and tanks due to their lightness and strength. They meet the strict requirements for safety and durability.

Advantages of deep-drawn parts:

• Deep-drawn parts are particularly strong and durable as they have no weld seams or other potential weak points.
• The deep-drawing process is economical for large production quantities and enables consistently high quality.
• Deep drawing can be used to produce complex geometries that would be difficult or impossible to achieve with other forming processes.
• The smooth and seamless surfaces are ideal for optical or hygienic requirements.
• As the material is formed into the desired shape, material consumption remains low.

Deep-drawn parts are important components used in various industries where stability, complexity and precision are required. The deep-drawing process enables the efficient production of components with seamless, smooth surfaces and high strength, making them a versatile solution for demanding industrial applications.

Below is an overview of the most important points to consider when purchasing deep-drawn parts:

When purchasing deep-drawn parts, it is important to pay attention to a variety of factors to ensure that the parts meet the requirements for quality, fit and durability.

• Choose the material according to the mechanical requirements, such as strength, corrosion resistance and temperature resistance. Typical materials are steel, stainless steel, aluminum, brass or suitable plastic foils.
• The material should have good ductility (malleability) so that it can be processed in the deep-drawing process without breaking or cracking.
• Corrosion-resistant materials such as stainless steel or plastic are particularly important for outdoor applications or in humid environments, such as in medical technology or the automotive industry.
• The components should meet the specifications exactly, especially if they are integrated into complex systems.
• Discuss the required tolerances in advance, especially for tight fits, as small deviations can lead to assembly or functional problems later on.
• For series production, high repeatability is essential to ensure that all parts are identical and fit accurately.
• For applications where appearance and hygiene are important, the parts should have a smooth, even surface.
• For increased resistance to corrosion or wear, additional surface treatment may be required, such as polishing, coating or passivation.
• For applications that are exposed to extreme temperatures, moisture or chemical influences, the material and surface treatment must be particularly resistant.
• For visible components, such as in consumer goods or medical technology, a flawless surface without scratches or grooves is required.
• Ensure that the deep-drawn parts remain stable and true to shape even with more complex geometries.
• Discuss the feasibility of complex geometries, as some shapes require special tools and materials.
• Depending on the complexity, several drawing stages may be required. Choose a supplier that has the expertise and equipment for multiple forming processes.
• Since deep drawing requires high-quality tools, the dies and punches used should be of high quality and precisely manufactured to ensure consistent quality.
• The manufacturer should have experience in deep drawing technology and be able to realize sophisticated geometries.
• A supplier with modern equipment and technology can offer more precise components and higher production quality.
• With high quantities, the cost per part decreases. Therefore, check whether the manufacturer is optimized for the planned production quantity.
• Choose a supplier who is able to react flexibly to changes in order quantities, especially in the case of new product developments.
• In addition to the unit price, you should also consider the costs for tools and, if necessary, surface treatments.
• A cheaper component can be more expensive in the long term if the quality is poor and frequent reorders or replacements are necessary.
• The manufacturer should be certified, e.g. to ISO 9001, and have a quality management system that ensures compliance with specifications and consistent manufacturing quality.
• In industries such as medical technology or the automotive industry, it is important that all materials and production steps are documented and traceable.
• Ask for test reports and quality certificates to ensure that the parts meet the required standards.
• Clarify delivery times in advance and check whether the manufacturer can guarantee a consistently short lead time, especially for large quantities or repeat orders.
• A reliable supplier should be flexible to your requirements and offer good customer support to resolve issues quickly.
• Check whether the supplier uses sustainable processes and whether the materials used are recyclable. A responsible supplier often meets environmental standards such as ISO 14001.

When purchasing deep-drawn parts, material selection, precision and surface quality are key. An experienced manufacturer with modern equipment and reliable quality control can deliver high-quality and durable deep-drawn parts. Especially when it comes to series production and complex shapes, it is worth choosing a partner that focuses on flexibility, precision and customer satisfaction.
