The Company

Global Zalmu was born from the expansion of Plásticos Zalmu (a company founded in 1958) . In its beginnings, its activity was focused on the transformation by injection of technical plastics, after these beginnings it incorporated design advice to its customers and other technologies in its products (wiring, PCB assemblies, assemblies) until today, in which it offers comprehensive solutions in design and manufacture of mechanical electrical-electronic systems and subsystems.

Global Zalmu has been expanding its business activity by manufacturing a wide variety of electrical and mechanical assemblies, which range from small electrical connections to complex industrial assemblies, or carrying out the assembly and soldering of printed circuit boards (PCB).

To meet customer needs, we offer the complete production process, from initial advice on the design of injection moulded parts to the different intermediate processes required to obtain the final product, including screen printing, thermo-stamping, ultrasonic welding, printed circuits, machining, wiring, etc.

The main sectors for which we carry out our activity are:

Aeronautics Transportation Electricity & Electronics
Sanitary Telephony Appliances
Automobile Packaging Elevators and Lifts
Signage Construction Agriculture

We currently have several facilities that allow us to keep the different production areas independent:

Our Job

Global Zalmu has a daily production day of 16 hours divided into two shifts, although this capacity can be extended if our clients require it. As reflected in our Quality Manual, we ensure our processes through a systematic monitoring of machine parameters, assembly certificates and the implementation of Self-Control and Inspection Guidelines, ensuring the quality and competitiveness of the company.

Plastic injection moulding

At Global Zalmu we have more than 50 years of experience in the world of plastics, through which we have evolved and implemented improvements in our machinery and technology to satisfy with the highest quality any production demand that our clients may have. To this end, we provide a comprehensive service based on:

  • Mould design
  • Technical advice
  • Optimisation of production
  • Injection moulding
  • Assembly or finishes such as chrome plating, gold plating, hot stamping, silk-screen printing...

Thanks to our team of machines and qualified personnel, we have the capacity to produce parts with inserts, stickers, drills, parts for chrome plating and even make assemblies on parts already injected.

We have 13 injection moulding machines working at full capacity for 16 hours of daily production, a human team supervising the operations and their parameters, and several robotic arms in charge of the extraction of the parts.

Our machines allow us to produce parts weighing up to 2,500 grams with a clamping capacity of between 45 and 800 tons

Industrial Assemblies

At Global Zalmu we work with a high degree of coordination in order to combine our different productions to assemble and mount highly complex products. The following tasks are carried out at the Industrial Assemblies work centre:

  • Assembly of injected parts for the aeronautical sector.
  • Assembly of electromechanical assemblies for the elevator industry.
  • Processing of ground wires for the aeronautical sector.
  • Electrical and/or electronic inspection of assembled assemblies.

In order to be able to carry out the tasks carried out in this work centre, we have a team of people trained to carry out any plan, respecting the client's indications and using a wide variety of tools.

On the other hand, as in the other two work centres, this centre has its own warehouse with an enormous diversity of articles of common or specific use for assembly, such as screws, brackets or specific products requested by the client for assembly.

In addition, for the processing of aeronautical ground wire, Global Zalmu has a workstation with the necessary machinery to manufacture the articles, such as wire cutters or automatic crimpers for different terminals.

Finally, it is worth mentioning the test equipment in this work centre, which is used to test the connections of those assemblies that include wiring.

Global Zalmu has a large main warehouse which allows us to store an enormous quantity of finished articles and raw materials necessary for production. Likewise, as mentioned above, each work centre has a smaller warehouse, reducing manufacturing times thanks to the physical stock present in each centre.

Similarly, it is worth highlighting the organisation of each work station, which is subject to a specific study for its organisation, facilitating the operator's task and reducing the manufacturing time of the processed articles.

We use the latest IT tools in order to coordinate the different warehouses and, thanks to our ERP, we are able to meet the deadlines demanded by the client, covering both their needs and our own.

For all these reasons, the quality of our service is remarkable, with total compliance with our commitments and deliveries.
