TTS GLOBAL
Find a material mismatch before it becomes a batch problem.
Problems in bulk production often start with the wrong material, missing components or an unconfirmed reference sample. A pre-production inspection focuses on what is available before manufacturing begins. TTS reviews the agreed inputs and preparation evidence so you can raise discrepancies before they are built into a full order. This service suits new products, new suppliers, important material changes and orders where colour, finish or component consistency matters.
What to check in the evidence
Material identity
Match supplier references, material batch labels and available certificates to the purchase specification or bill of materials (BOM).
Why it matters
A similar colour or appearance does not establish that the specified resin, fabric or component was supplied.
Approved reference
Confirm which sealed sample, drawing revision, colour reference and measurement sheet governs production.
Why it matters
Conflicting sample versions create disputes later. Record the controlling reference and unresolved differences before release.
Available quantity
Compare usable material and component quantities with the planned order, including shortages and material awaiting approval.
Why it matters
Production readiness depends on the required component set, not just the presence of the main material.
First-piece readiness
Review the initial assembly or first-off sample where available, tooling readiness and the factory’s incoming-quality-control (IQC) records.
Why it matters
Decide which concerns must be resolved before bulk production and which need a targeted during-production check.
An illustrative scenario
One changed component can affect the entire order.
Illustrative example: the approved sample uses one zipper, while the warehouse contains a visually similar replacement. Record the markings and compare dimensions, function and construction with the approved reference. Ask for buyer approval or the specified component before production consumes the stock. Any laboratory performance requirement remains a separate item in the test plan.
Prepare these before the next step
- Bill of materials and quantities for the order.
- Approved sample, colour references and component specifications.
- Factory address, contact, material arrival dates and production schedule.
The findings help you request replacement material, clarify an instruction or agree the next production checkpoint. Materials that are unavailable during the visit remain outside the observed result; chemical composition or other hidden properties may require laboratory testing.
