Material certificates and test reports may be necessary when plastic tooling supports a regulated product. Whether they are required depends on the product’s applicable standards and documentation rules. The available details for Longterm’s custom double-shot overmolding mold describe tooling inspections and the company’s quality certification, but do not confirm that material certificates or regulatory-specific reports are supplied. Define the documentation requirements with the supplier before ordering.
The custom tool is designed for two-color injection molding and hard-soft material combinations such as ABS+TPU and PP+TPE. The product details also identify 718H / 1.2738 mold steel and describe high-precision alignment.
Listed quality checks include a mold trial run, dimensional testing, and pre-shipment inspection. These checks can provide evidence about mold operation and dimensions, but the available information does not say they replace material certificates or product-specific compliance testing.
Longterm lists ISO 9001:2015 certification, certificate number 02825Q12549R0S, for precision mold design, manufacturing, and sales, as well as the sale of plastic products. No additional regulatory approval is identified in the supplied product information.
Documentation obligations vary according to the regulated product and its intended market. Ask the tooling supplier which records can be provided for the selected materials, and state the required test methods, report contents, and acceptance criteria in the quotation or purchase specification. Obtain written confirmation before production begins.
Longterm lists consumer electronics and home appliance parts among its injection mold applications. One project example is a double-shot overmolding mold for a consumer electronics shell supplied to a French product brand; feedback cited good alignment and stable trial samples. Another listed project involved an electronic housing mold for an Italian manufacturer. These examples describe tooling projects and customer feedback, not proof of particular material-documentation or regulatory requirements.

| Topic | Stated information | Buyer follow-up |
|---|---|---|
| Material certificates | Not confirmed in the product details | Ask whether certificates can be supplied for the chosen materials and what details they contain |
| Testing and inspection | Mold trial run, dimensional testing, and pre-shipment inspection are listed | Specify required reports, test procedures, and acceptance criteria |
| Quality certification | ISO 9001:2015 is listed for the stated mold and product business activities | Determine whether it meets your supplier qualification requirements |
| Tool specifications | Two-color structure, ABS+TPU and PP+TPE compatibility, and 718H / 1.2738 mold steel | Confirm the design and material combination against the approved specification |
The provided details do not state that material certificates are included. Confirm availability and the required certificate information directly with the supplier before placing an order.
The listed checks are a mold trial run, dimensional testing, and pre-shipment inspection.
No such claim appears in the supplied information. It identifies ISO 9001:2015 for specified business activities, but does not establish compliance of a finished regulated product.
Do not assume that material certificates or regulatory test reports come with the tooling; the product details do not specify them. Before approving the order, agree with the supplier on required documents, applicable tests, and acceptance criteria.
