We use high-quality metal and mineral materials to ensure the durability and stability of the parts. All materials are subjected to strict quality control and inspection to ensure compliance with international standards.
Chapter 2
Cutting And Shaping
The raw materials are laser cut or stamped to the desired shape and size. According to the product requirements, the use of stamping machines, shear machines or CNC machines to accurately cut and shape the material to ensure the dimensional accuracy of each part.
Chapter 3
Welding And Assembling
Where welding is required, parts are joined by hand or Robot welding. All welding points are strictly inspected to ensure the welding quality without defects and the overall structural stability of the parts.
Chapter 4
Surface Treatment
In order to enhance the corrosion resistance and beauty of the parts, surface treatment is an essential step. Common treatment methods include spraying, zinc plating, chromium plating, etc. . We use advanced surface treatment technology to ensure that the surface of the parts smooth, uniform and enhance their durability.
Chapter 5
Inspection And Testing
Every metal part is subjected to strict quality inspection. We use precision instruments to test the size, strength and hardness of the parts to ensure compliance with industry standards and customer requirements. Only parts that pass the test can move on to the next stage.
Chapter 6
Packaging And Shipping
Conforming parts are cleaned and packaged to ensure that they are not damaged during transport. We use high-quality packaging materials and provide customized packaging to ensure that the parts arrive safely at their destination.
Surface Treatment for High-Performance Mining & Quarry Wear Parts
For crusher liners, chute liners, wear plates, buckets, and high-impact wear components—PRIME combines coating/overlay options with controlled prep + inspection to help you reduce downtime and stretch replacement cycles.
What Surface Treatment Solves in the Field
- Slide abrasion (chutes, liners, conveyors): reduce rapid metal loss.
- Gouging + impact (crusher zones, buckets): improve edge retention & crack resistance.
- Wet + corrosive environments: add barrier protection where needed.
- Heat + friction points: keep hardness stable and surfaces consistent.
Common Surface Treatment Options for Wear Parts
Selection depends on wear mechanism (abrasion / impact / corrosion), base material, and the CTQ wear zones.
Hardfacing Overlay (Wear-Resistant Build-Up)
Ideal for high-abrasion areas. Controlled overlay patterns help maintain coverage and minimize distortion.
Thermal Spray / High-Velocity Coatings
For precise thickness control and lower heat input. Great when dimensional control is tight.
Heat Treatment + Surface Strengthening
Improves core toughness and surface hardness balance—useful for impact zones and crack resistance.
Anti-Corrosion / Barrier Finishes
For wet quarries or chemical exposure—use coatings to protect non-wear areas and extend overall life.
Our Surface Treatment Workflow (Repeatable + Documented)
A clean surface, controlled parameters, and verification at each gate—this is how we keep batches stable.
-
01DFM + Wear-Zone MappingConfirm CTQ wear surfaces, build-up limits, and areas that must remain machinable.
-
02Surface Prep for AdhesionDegrease, blast/roughen, remove oxides, and mask non-coat areas for clean boundaries.
-
03Apply Overlay / CoatingControlled parameters (heat input, passes, thickness range) to reduce distortion and defects.
-
04Post-ProcessingGrinding, blending, and machining allowances to meet fit-up and assembly requirements.
-
05Inspection + RecordsThickness checks, hardness verification, visual criteria, and batch traceability as required.
-
06Protective Packing for ExportAnti-rust protection, separators, and labeling to prevent coating damage in transit.
