Contract Assembly and Subassembly in San Luis Potosí - RIDYS Group

Contract Assembly and Subassembly

When External Contract Assembly or Subassembly Is Needed

You have a demand peak your line cannot absorb and building your own capacity is not justified. You need to free up floor space and staff to focus on your core process. Or you need a subassembly operation your plant is not set up to run.

What We Do

We perform contract assembly, subassembly, and assembly of components or finished product, with trained personnel, at our facilities or inside yours.

The scope is defined against the specification you provide: drawing, work instruction, visual aid, or master sample. No operation runs without a previously documented criterion.

How the Operation Is Set Up

Start-up follows a fixed sequence.

First, we evaluate the product specifications and service requirements and design the assembly process. Then we select and train personnel for that specific operation, not generically. Then we set up the line: equipment installation, workstation setup, and process validation before full production.

Series production starts only once that validation passes.

Quality Control Is Built In, Not Added at the End

This is the difference from conventional contract assembly.

Inspection is not performed only on finished product: it is built into the process, with verification points defined in the work instruction. If a deviation is detected, it is contained at the station where it occurred, not downstream.

For us, contract assembly is an extension of quality control, not a manufacturing operation with a check at the end. It is the same discipline we apply in inspection and containment, applied to a production operation.

Capacity, Scaling, and Infrastructure

Capacity adjusts to your demand, without you investing in your own infrastructure.

When the service requires it, we provide the necessary capital investment: equipment, workbenches, tools, measuring instruments, gauge supply, and tooling fabrication.

What You Receive

Production record with lot traceability, inspection results, and disposition of nonconforming material. Report frequency is agreed with each customer.

The packaging, preparation of the shipment and logistical coordination for delivery are part of the service when contracted.

Backup

ISO 9001:2015 certification (Orion Registrar, ANAB accredited) and REPSE (Mexico’s Registry of Specialized Service Providers) registration ARR197/2024 with Mexico’s Ministry of Labor (STPS). Personnel with DC-3 certificates and documented training records. Our processes are carried out in accordance with our customers’ IATF 16949 requirements.
