Three-Stage
Quality Control
All raw materials are inspected against mill certificates. Chemical composition, hardness, and dimensional checks are completed before any production begins.
SPC monitoring at critical machining stages. First-off, mid-run, and last-off parts are checked by CMM and gauge. Non-conformances stop production immediately.
SSPrecision checks critical features against the agreed inspection plan. Dimensional reports, material certificates and PPAP are prepared when specified in the order.

Common
Questions
Explore our company profile, manufacturing expertise, quality control, company history and buyer FAQs.
Contact Our TeamSSPrecision uses a documented quality management system to control processes and address non-conformances. First, request the current certificate and its scope. Then agree traceability, inspection and acceptance requirements for your order. System certification does not replace product testing or guarantee each part meets an unstated specification.
Before supplier approval, check that the company name, manufacturing address and covered activities match the work you intend to purchase. Also check the certificate dates and issuing body. If your purchasing procedure requires independent verification, complete that review before releasing the order.
Next, identify the records your team needs at incoming inspection. For example, distinguish a material certificate from a dimensional inspection report. Each document supports a different requirement. Therefore, list both the required evidence and the acceptance criteria in the request for quotation.
For repeat orders, agree how drawing revisions, approved deviations and process changes will be communicated. A revision number on every technical document helps avoid misunderstandings. Similarly, define who can approve a change and when written approval is required.
If a discrepancy occurs, provide the order number, affected quantity, photographs and measurement results. Include the measurement method where relevant. This information helps engineering compare the reported issue with the agreed specification and propose an appropriate response.
Finally, treat supplier qualification as an ongoing process. Review delivery performance, inspection findings and corrective actions against your own purchasing criteria. Ask SSPrecision to confirm any project-specific audit or record-retention requirement during quotation, rather than assuming it forms part of every order.
SSPrecision supplies tooling and components for automotive, electronics, industrial machinery, medical-device and aerospace projects. Since 2008, our work has included progressive stamping dies and die components. However, each application needs its own material, documentation and approval review before supply is confirmed.
First, explain what the part does and the conditions it will encounter. Loading, temperature, corrosion exposure and expected service life can influence the material and process review. Where possible, identify the mating components and the features that control fit or movement.
Next, separate a replacement component from a new tooling development project. A replacement may require checking wear patterns or compatibility with an existing assembly. A new design may need additional drawing clarification, sample evaluation or production validation before volume purchasing.
For automotive purchasing, specify any required submission package and customer-specific documents. Similarly, medical and aerospace buyers should identify their own qualification, traceability and regulatory obligations. Supplying a component does not, by itself, establish approval for a regulated end use.
If your company uses an approved-supplier process, send its technical and quality requirements with the enquiry. This allows the team to assess the requested work before making commitments. In addition, flag restricted materials, special cleaning or identification requirements early.
Finally, provide the expected order quantity, repeat demand and target delivery date. These details help distinguish prototype needs from ongoing production supply. SSPrecision can then review the drawing, manufacturing route and documentation together, so that the quotation reflects the actual application rather than a general industry label.
SSPrecision lists indicative capabilities of ±0.002mm for selected die features, ±0.005mm for milled features and ±0.003mm for wire EDM. However, achievable results depend on material, geometry, datum strategy and measurement conditions. Send the drawing first so engineering can confirm tolerances and the inspection plan.
First, mark the dimensions that affect assembly, function or interchangeability. Then distinguish those critical features from general drawing tolerances. Applying the same tight limit to every surface can add work without improving the performance of the finished assembly.
Next, identify the applicable drawing standard, units and revision. Define datums clearly and avoid conflicting dimensions between a model and a drawing. If both files are supplied, state which source takes precedence when the two contain different information.
Material condition also matters. Heat treatment, coating thickness and residual stress can influence the final dimensions. Therefore, specify whether acceptance applies before or after these operations. Surface finish requirements should identify the relevant surfaces and the required measurement parameter.
For inspection, agree the measurement method and any special fixture or sampling requirement. Also state whether results must be reported for every part or selected samples. A numerical tolerance alone may not fully describe how two teams should establish conformity.
Where the design is still developing, request a feasibility review before freezing the specification. Engineering can identify unclear features or discuss alternatives for your approval. SSPrecision confirms the accepted drawing and inspection scope in the project documentation; published capability figures remain references rather than unconditional guarantees for every geometry.
First, specify the dimensional reports, material heat numbers, hardness records, finish measurements and photographs your receiving team needs. SSPrecision can review PPAP Level 3 requirements for automotive projects. Documentation scope, language and any additional work are confirmed in the quotation; every order has its own agreed requirements.
Start with a document list linked to the drawing revision and purchase order. For example, name the dimensions to be reported and the format your quality team can accept. This is more useful than requesting a general quality package without defining its contents.
Next, explain the required relationship between each record and the delivered parts. Depending on the specification, traceability may be established by batch, material heat, order line or individual identification. The proposed approach should be agreed before manufacturing and marking begin.
If material certification is required, specify the material designation and the certificate type expected by your receiving procedure. Similarly, request treatment or coating records when those processes form part of the acceptance criteria. Do not assume that one certificate covers every manufacturing operation.
For dimensional reporting, distinguish first-article approval from routine shipment inspection. State the sampling plan, reporting units and any required signatures. In addition, identify whether your company needs electronic files before dispatch so that document review can be scheduled.
Finally, agree how long project records must remain available and how replacement copies can be requested. SSPrecision can review these requirements during quotation. Defining the document package at the start helps your purchasing, engineering and receiving teams evaluate the same evidence when the order arrives.
SSPrecision serves customers across Europe, North America and Asia, including Germany, Slovenia, the UK, USA, Japan and South Korea. Our export team coordinates packaging, customs documents and freight arrangements. Confirm the destination, delivery term and importer responsibilities when requesting a quotation.
First, provide the full delivery address and indicate whether the goods will go to your factory, a warehouse or a logistics partner. Also identify any receiving appointment, labelling or packaging instruction that could affect dispatch preparation.
Next, agree the delivery term and named place in the quotation. This helps both parties understand the allocation of transport responsibilities and costs. Duties, taxes, customs clearance and insurance should be reviewed explicitly rather than assumed from a general shipping estimate.
For packaging, describe any corrosion protection, individual separation or reusable-container requirement. Precision surfaces and fragile features may need particular handling precautions. In addition, tell the team if the receiving site restricts packaging materials or requires specific package identification.
Before dispatch, confirm the commercial details needed for the shipping documents. Product descriptions, quantities and consignee information should match the order. Where classification or import permission needs specialist advice, involve your customs broker or the responsible authority for the destination.
Finally, distinguish the manufacturing completion date from the expected arrival date. Transport schedules and clearance can affect delivery after the goods leave the factory. Ask SSPrecision to confirm the proposed shipment method, document handover and tracking arrangements before authorizing dispatch, especially when your production schedule depends on a fixed receiving window.
