Surface Finishes
We offer a variety of surface treatments to meet functional and cosmetic needs:
As-Cast: The natural surface from the mold, suitable for parts that will be machined later.
Shot Blasting: Cleans the surface and creates a uniform matte finish, improving paint adhesion.
Grinding & Polishing: Achieves a mirror-like or satin finish for aesthetic components.
Powder Coating: Provides a durable, decorative, and corrosion-resistant colored finish.
Plating: Including Nickel, Chrome, and Zinc plating for extreme corrosion resistance and a classic glossy look.
Heat Treatment: Processes like quenching & tempering, and annealing to enhance hardness, strength, and wear resistance.
Anodizing (For applicable alloys): Creates a hard, decorative, and corrosion-resistant oxide layer.
Company Advantages
1.High Precision & Complexity: The silica sol process allows us to produce parts with excellent surface finish (Ra 3.2μm achievable), tight dimensional tolerances (±0.005mm/in), and incredibly complex geometries that are impossible with other methods.
2.Material Expertise: Deep knowledge of metallurgy allows us to recommend the optimal material for strength, weight, and cost requirements.
3.Integrated Service: We offer end-to-end solutions from design assistance and prototyping to casting, heat treatment, machining, and surface finishing.
4.Quality at Competitive Cost: Our efficient process minimizes material waste and secondary machining, delivering high value without compromising on quality.
5.Proven Reliability: Our components are trusted by manufacturers and custom builders for their consistency and performance in demanding conditions.
Quality Inspection Steps
We enforce a rigorous, multi-stage Quality Control (QC) system to ensure every part meets the highest standards.
1. In-Process Inspection (IPI):
Wax Pattern Inspection: Dimensional checks of wax patterns.
Shell Inspection: Monitoring of each ceramic shell layer for integrity.
Material Verification: Spectrometer analysis of raw alloys to ensure correct chemical composition.
2. Final Inspection (Pre-Shipment):
Dimensional Inspection: Using calibrated tools (Calipers, Micrometers) and Coordinate Measuring Machines (CMM) for critical dimensions and GD&T analysis.
Visual Inspection: 100% visual check for surface defects like porosity, cracks, or inclusions.
Hardness Test: Brinell (HB) or Rockwell (HRC) tests on sample parts to verify heat treatment and material strength.
Mechanical Property Testing: Tensile and yield strength tests are performed on separately cast test bars from each production melt.
