Manufacturing Support: CNC, Sheet Metal, Molding and PCBA

Opotek prepares manufacturing-ready files and manages suppliers for machined, sheet-metal and molded parts plus PCB assembly, in Spain/EU or Asia depending on volume and cost. We manage these processes through suppliers; we do not run the machines ourselves.

  • Based in Barcelona
  • NDA by default
  • IP ownership: your choice

Which processes do you support?

  • CNC machining in aluminium, steel and plastics.
  • Sheet metal: laser cutting, bending and finishing.
  • Injection molding: tooling, minimum quantities and when to switch from 3D printing.
  • PCBA: turnkey or consigned, component sourcing and alternates.

How do you choose suppliers and control quality?

Suppliers are chosen per project on cost, lead time and quality needs, with incoming inspection and first-article checks defined in the production documentation.

Local or Asian manufacturing?

Local (Spain/EU) manufacturing gives shorter lead times and easier communication at low volume; Asia gives lower unit cost at higher volume. We help you weigh both.

Frequently asked questions

Do you manufacture the parts yourselves?

No. We prepare the files, select and manage the suppliers, and validate the first units.
