Yes. Buyers can make plastic tooling documentation a contractual requirement to help prepare for future product safety audits. Longterm’s product information identifies mold trial testing, dimensional inspection, and a full pre-shipment check for its custom electronic-housing injection mold. It does not, however, define a standard documentation package. Agree in advance which records the supplier will retain and deliver.
The listed quality activities provide a starting point for defining audit evidence. Buyers should confirm whether each activity produces a written report, measurement data, identified samples, or other records. The product information does not specify report formats, record retention periods, or whether sample approvals are documented.
The electronic-housing mold is described as suitable for ABS, PC, and PP, with a stated precision tolerance of ±0.02 mm. Mold configurations may be single- or multi-cavity. If audit requirements apply to a particular resin, dimension, or part revision, identify those requirements in the purchase specification and link the inspection evidence to the approved sample.
| Record or control | Information provided | Details to agree with the supplier |
|---|---|---|
| Mold trial | Mold trial testing is listed among the quality inspections. | Whether trial conditions, results, and sample identifiers will be recorded and supplied. |
| Dimensional inspection | Dimensional inspection is listed, and the product states a ±0.02 mm precision tolerance. | Which characteristics will be measured and whether dated reports or raw data are included. |
| Pre-shipment check | A full check before shipment is listed. | The inspection scope, acceptance criteria, and evidence provided to the buyer. |
| Sample approval | The company profile refers to sample confirmation in some service models; product-specific signed approval records are not confirmed. | Whether sign-off is required and how the approved part revision will be identified. |
The stated mold materials include P20, 718H, and 1.2738. Available surface finishes include polishing, texture, and matte, and the stated mold life ranges from 50,000 to 800,000 shots. These specifications may help define the scope of an order, but they do not by themselves establish what audit records will be provided.
Longterm’s company profile lists ISO 9001:2015 certification for the design, manufacture, and sale of precision molds and the sale of plastic products. It also describes an electronic-housing mold project for an Italian customer and an industrial plastic-part mold project for an Australian customer. The summaries refer to dimensional precision and technical problem-solving, but do not detail the documentation delivered. They indicate relevant experience, not a commitment to a particular audit file.
Yes. List the required records in the purchase specification and obtain written confirmation from the supplier. The product information names mold trial testing, dimensional inspection, and a full pre-shipment check, but does not promise specific reports or formats.
No. It describes inspection activities and after-sales services such as online technical guidance, mold maintenance, and spare-parts support. It does not state that a complete audit dossier, a defined retention period, or regulatory documentation is included.
Specify the mold and part identifiers, material, approved sample revision, inspection characteristics, acceptance criteria, required records and file formats, and the timing and retention period for delivery. Confirm these terms before production begins.
To support future safety audits, define the tooling records you need in the purchase requirements and confirm exactly what the supplier will deliver. The available information supports requests for evidence of mold trials, dimensional inspections, and pre-shipment checks, but does not establish that a formal audit package is standard. Longterm Mold lists OEM custom mold making, mold making with injection molding, precision and overmold tooling, and mold development with mass production among its service models.
