01 / ABOUT WONTIDE
Meet the people
behind the parts.
Established in 2005 in Laizhou, China, Wontide manufactures industrial components with steel casting at the core. In-house heat treatment and machining connect the manufacturing route; sheet metal fabrication and welding are also available as an independent business.
We work from customer drawings, review manufacturing requirements and connect the processes needed for the part. Experience includes axle and suspension components, commercial vehicle brackets, steel valve components and cast steel pile tips.

Connected processes.
A clearer path to your part.
Bring the material, casting, heat treatment and finishing requirements together at the technical review. Then agree the manufacturing route for your component.
01Casting
Shell mould casting for steel components. Material specifications, casting geometry and inspection requirements are reviewed before tooling.
02Heat treatment
Normalizing, quenching and tempering to the agreed material condition. Treatment requirements and mechanical properties follow the approved technical specification.
03Machining
CNC machining of cast blanks and drawing-defined components. Datums, fits, critical dimensions and inspection requirements are established during the technical review.
03 / QUALITY
The drawing sets
the standard.
Material verification, dimensional inspection and agreed documentation connect the technical requirements to the delivered component.
QUALITY MANAGEMENT SYSTEMIATF 16949:2016
Certificate scope covers the manufacture of iron and steel castings and sheet metal weldments. Manufacturing is based on customer-approved drawings.

PRODUCT & SOURCING GUIDES
Find your component.
Define the requirements.
Explore drawing-based steel casting families, then prepare the information needed for a manufacturing review.
Leaf spring seatsFor buyers sourcing a drawing-defined spring seat, the technical review begins with the axle interface, spring contact geometry and required delivery condition. The photographed component is a representative example; a new project follows its own approved drawing.↗Torque rod bracketsFor a suspension bracket enquiry, identify the assembly interfaces and the relationships between bores, mounting faces and holes. Upper, lower and combined versions should be identified by their own drawing numbers and revisions.↗Spring plates & padsA useful enquiry distinguishes the function and interfaces of each plate or pad. The product name alone does not define the contact profile, mounting features, material condition or finish needed for a particular suspension assembly.↗Lift & swing armsFor an arm component, distinguish the cast geometry from finished machining features. The enquiry should identify the interfaces and dimensional relationships required by the assembly, together with any work to be completed after delivery.↗Valve bodies & bonnetsPlease include pressure-related testing and documentation requirements at the enquiry stage. A valve component drawing, its material specification and its examination requirements need to be considered together before the supply scope can be confirmed.↗Cast steel pile tipsFor a pile tip enquiry, include the component geometry and the interface connecting it to the next part. Supply any foundation-project requirements that affect material, manufacture, inspection or identification of the component.↗

Before we talk
Do you manufacture to customer drawings?
Yes. Steel castings, machined components, sheet metal parts and welded assemblies are evaluated against the customer’s drawings and technical requirements.
Which processes are in-house?
Casting, heat treatment, machining, sheet metal fabrication and welding are in-house. Galvanizing and electrophoretic coating are arranged through external suppliers when required.
Can you support PPAP and inspection documents?
We can support PPAP and inspection documentation. The submission level, tests, sampling and acceptance requirements should be agreed for the specific project.
What should I send for a technical discussion?
Please include the current drawing revision, material specification, estimated quantities, critical quality requirements and required surface treatment. Add relevant 3D files or sample information if available.
Do you also review ductile iron enquiries?
Yes. Ductile iron enquiries are reviewed separately against the drawing, material specification, quantity and inspection requirements. Acceptance is confirmed for each project.
