Metal stamping, welding and assembly
Manufacture of metal components and sub-assemblies for the automotive and industrial sectors, with integrated stamping, welding, assembly, coating, and logistics processes.
Grupo Marsan offers industrial capacity for the series production of metal parts, combining metal transformation, joining processes, industrial coatings, and logistical support for demanding programmes.
Metallic transformation for industrial components
Metal stamping allows for the manufacture of parts and components from sheet metal through cutting, forming, folding, and deep drawing processes, tailored to the technical requirements of each project.
At Grupo Marsan, we work with processes oriented towards serial production, where dimensional stability, repeatability, component quality, and integration with subsequent processes are key factors.
An industrial solution for customers requiring metal parts, welded sub-assemblies, assembled components, or integrated solutions with coating and logistics.
Main processes
We integrate metal transformation, joining, assembly, and coating processes to offer industrial solutions tailored to automotive and industrial programmes.

Progressive embossing
Manufacture of metal components using cutting, forming and sheet metal processing for series production.

Welding
Joining processes for metallic components and sub-assemblies, focused on strength, repeatability, and quality requirements.

Assembly
Assembly of sub-assemblies and complementary operations to deliver parts ready for integration into the customer's supply chain.

Integration with coating
Possibility of combining metallic transformation with electrophoretic deposition, powder coating, liquid painting, or combined coating systems.
Quality, repeatability, and industrial control
Stamping and welding processes require dimensional control, process stability, and monitoring of the technical requirements defined by the customer.
Grupo Marsan, formerly Marsan Group, directs its operations towards demanding industrial environments, focusing on repeatability, traceability, documentation control, and compliance with automotive and industrial requirements.
- Dimensional control of components.
- Process parameter tracking.
- Control of welded or assembled subsets.
- Project document management.
- Production traceability.
- Integration with coating and finishing requirements.
- Support during industrialisation and validation.
When to choose stamping and welding with Grupo Marsan?
This capability is particularly suitable for customers looking to manufacture metal components or sub-assemblies, especially when the project requires subsequent coating, assembly, or logistics processes.
- When metal parts are needed in series production.
- When the component requires soldering, assembly or fitting.
- When the part needs cataphoretic coating, powder coating, or subsequent liquid painting.
- When seeking to reduce intermediary suppliers.
- When you need technical support during industrialisation or transfer.
- When the project requires packaging, logistics or JIT deliveries.
The advantage of integrating stamping, coating, and logistics
Fewer intermediate suppliers
A single point of contact for metal transformation, coating, assembly, and supply processes.
Better coordination
Alignment between part design, coating requirements, tooling, handling, packaging, and logistics.
Logistical complexity reduction
Fewer movements between suppliers and greater control over deadlines, packaging, deliveries and material flow.
Better quality control
Integrated process monitoring, from the metal part to final finishing and customer delivery.
Support for serial programmes
Capacity to support industrial programmes with requirements for volume, traceability, and supply stability.
Industrial flexibility
Adaptation to projects with specific needs for capacity, coating, assembly, or JIT supply.
Assembly of components and laser stripping on painted parts
Grupo Marsan can integrate assembly operations and the application of auxiliary components onto already painted or coated parts, allowing for the delivery of sub-assemblies with a higher level of finish and preparation for the customer's line.
These operations can include the application of adhesive elements, soundproofing, protective coatings, functional components, or specific references defined by the programme, with integrated process control and verification. We also carry out laser paint stripping for specific areas.
- Application of auxiliary components onto painted parts.
- Integration with painting, coating, and logistics processes.
- Manual, semi-automatic or robotised operations depending on the project.
- Positioning, presence, and quality control.
- Reduced downstream operations for the customer.
- Delivery of parts ready for online integration.
Common applications
Stamping, welding, and assembly processes are applied to metal components that require dimensional stability, mechanical strength, and industrial production capacity.
Automotive metal components
Stamped parts and metal sub-assemblies for automotive programmes, and Tier 1 and Tier 2 supply chains.
Supports and structural parts
Metal components subjected to strength, geometry, assembly and stability requirements in series production.
Welded subsets
Parts made up of several components joined by welding or assembly processes.
Parts with rear coating
Metal components requiring anti-corrosion protection, surface finishing, or integration with painting processes.
