Document support
Company records and order-specific documents.
Yigao's official Chinese website has a two-page Qualifications and Honors index displaying company qualification and patent-certificate images. For an equipment order, Yigao lists the documents applicable to the selected model, components and destination market in the quotation.
Selected patent-certificate labels visible on the Chinese records page
The published subjects include an energy-saving mold temperature machine, an oil-circulation temperature-control machine for a molding press, a circulating heating device, an automatic-cleaning mold temperature machine, a cooling-protection device, a mold temperature machine heating tube and a vibration-protection mold temperature machine.
Patent number, Chinese title, owner, filing and grant dates and product relevance can be prepared when those details are required for procurement.
Document fields buyers should request
Company document
Legal entity, unified social credit code or registration number, registered address, issue authority and current status.
Certificate or type test
Document number, standard, issuing or testing body, issue date, expiry date, model scope and configuration limitations.
Patent record
Patent number, title, owner, inventors, application and grant dates, legal status and relevant product feature.
Inspection record
Order or serial number, drawing revision, test item, method, instrument, measured result, acceptance criterion, date and sign-off.
Model-specific inspection and testing to agree before order
The correct test package depends on the heater type. Buyers and Yigao should agree the inspection and test plan before production. Typical review items may include:
- Approved drawing, nameplate data and bill-of-material or key-component verification.
- Electrical protective devices, grounding, insulation resistance, phase sequence and wiring checks.
- Sensor, alarm, emergency stop, low-flow, low-level, over-temperature and other applicable interlock tests.
- Leak, pressure or circulation checks where the selected equipment and medium require them.
- Functional operation under an agreed safe test method, with operating assumptions and measured results recorded.
- Appearance, dimensions, connection direction, accessories, document package and export packing inspection.
Document scope
Certification, testing and inspection documents are matched to the selected model, components, destination market and agreed order requirements. The applicable package is listed with the quotation.
Buyer FAQ
Certificates and testing FAQ
Which certification documents are available?
Document availability depends on the selected model, components and destination market. State the required standard and destination country in the inquiry so the applicable document package can be listed in the quotation.
What information is available for listed patent references?
The official Chinese honors page displays certificate-image titles. Patent number, owner, grant date, current status and product relevance can be provided or checked when a project requires those details.
Which test records should be requested with an industrial heater?
The required records depend on the equipment. Typical items to agree in writing include drawing and component verification, electrical protection checks, grounding, insulation resistance, phase sequence, alarm and interlock tests, leak or pressure tests when applicable, functional operation and packing inspection.
Can a company-level qualification be used for every custom machine?
Not automatically. A company qualification and a product-specific certificate or test report serve different purposes. Ask Yigao to identify the document owner, scope, model, standard, issue date and destination-market applicability.
How should certificate requirements be written into an order?
List each required standard or document in the inquiry and quotation, then record the applicable model, issuing or testing body, acceptance criteria, delivery stage and whether an original, copy or independent inspection is required.
