Can I know how my products are going on without visiting?

We will offer a detailed production schedule and send weekly reports with photos or videos showing the machining progress.

Can I have a trial order or samples only?

As the product is customized, we charge sample cost. However, if the sample is not more expensive, we will refund the sample cost after you place mass orders.

Why is there a tooling cost?

It is the mold cost, an indispensable production process. You only need to pay for the first order, and we will bear the maintenance cost of mold damage.

AI-Powered supplier vetting

SummaryMatech Team demonstrates broad customization, OEM/ODM availability, documented quality and service procedures, ISO9001:2015 and RoHS certifications, and stated experience in valve making, foundry, mechanical engineering, manufacturing, and quality assurance. It reports new products within the past year and offers customization from samples, designs, and full specifications. Production information includes machining equipment and two production lines, but it does not conduct ongoing quantity reconciliation for every batch or volume production. Export sales represent 71%–90% of total sales, with three experienced export staff and one presence in a main export market. The supplier lacks overseas warehouses, showrooms, agents or branches, and has not participated in offline trade shows. Financial records are identified for 2022–2024, but the slices do not provide financial performance values. Customer evidence includes OEM service for well-known brands and an 80%–100% repeat-buyer preference, but no Fortune...

Supplier typeThe supplier provides manufacturing and engineering support, including OEM and ODM services, while describing experience in valve making, foundry, mechanical engineering, manufacturing, and quality assurance. Its listed machining equipment and customization services indicate a manufacturer with design-support capability rather than a trading-only profile.

CertificationsThe supplier reports an ISO9001:2015 management-system certificate and RoHS product compliance certification. These are explicit certifications supporting quality-management and product-compliance capability.

After-Sales capabilityThe supplier has written procedures and followed records for service-capability assessment, corrective and preventive actions, and effective customer-complaint handling. However, the approved-supplier list lacks an approved signature or date, which indicates a documentation weakness but does not establish inadequate after-sales execution.

R&D capabilityThe supplier states that it introduced new products during the past year, offers ODM services, and provides early design support and manufacturing-feasibility analysis. It does not have an available SDK, but the available evidence still explicitly supports product-development and design-input capability.

Production capacityProduction resources include lathes, CNC, drilling and automatic tapping machines, a hydraulic pressure test pump, and two production lines. The supplier reports one-month average lead times in both peak and off-season periods, but it does not perform ongoing quantity reconciliation for each batch or volume production, creating a stated production-control weakness.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. The same broad capability is reported in two slices, providing strong direct evidence of extensive customization coverage.

Client casesThe supplier reports OEM service for well-known brands, more than twenty years of team experience in relevant technical and manufacturing areas, and an 80%–100% preference from repeat buyers. It reports no cooperation with Fortune 500 companies, so customer-case evidence is positive but does not establish top-tier multinational references.
