-
Q How do you protect customer drawings and intellectual property?
A We sign Non-Disclosure Agreements (NDAs), strictly control document access, and can delete or return data upon project completion as requested.
-
Q How are castings packaged and shipped?
A We use customized packaging (anti-rust paper, foam boxes, wooden crates, etc.) based on part characteristics and provide global logistics support.
-
Q Do you allow customer site audits or production process monitoring?
A Customer visits and audits are welcome. We can also share production progress via photos, videos, or regular reports.
-
Q How are casting defects handled?
A In case of quality issues, we perform root cause analysis (e.g., process, material, or design) and offer free re-production or compensation according to the agreement.
-
Q Do you offer secondary machining and surface treatment services?
A We typically provide one-stop services, including heat treatment, shot blasting, polishing, plating, painting, CNC precision machining, and more.
-
Q What are the main factors affecting the quotation?
A Key factors include material cost, part complexity, order quantity, post-processing requirements (heat treatment, machining, coating, etc.), and tolerance specifications.
-
Q Do you provide DFM (Design for Manufacturability) analysis?
A Yes. Upon receiving drawings, we provide detailed DFM feedback to help optimize the design for improved yield and cost control.
-
Q What key points should be considered in casting design to reduce cost?
A We recommend avoiding sharp corners, optimizing uniform wall thickness, designing appropriate draft angles, and minimizing post-casting machining requirements where possible.
-
Q How do you control quality during the production process?
A We implement full-process monitoring (e.g., wax pattern, shell building, melting) and conduct first-article inspection, in-process checks, and final inspection.
-
Q What international certifications does the factory hold?
A Common certifications include ISO 9001, DNV,GL,LR and BV.
-
Q Do you provide material certifications and test reports?
A Yes. Certificates such as EN 10204-3.1/3.2 material reports and non-destructive testing reports can be provided for each batch.
-
Q What quality inspection methods do you employ?
A We use Coordinate Measuring Machines (CMM), spectrographic analysis, X-ray inspection, liquid penetrant testing, mechanical property testing, etc., to ensure compliance with standards.
-
Q Can you cast complex internal channels or thin-walled structures?
A Yes. Investment casting excels at complex geometries. Minimum wall thickness can be as low as 0.5 mm (material-dependent), and hollow structures are achievable.
-
Q Which materials are suitable for investment casting?
A Common materials include stainless steel, alloy steel, carbon steel, copper alloy, etc. Material certification is available.
-
Q What is the maximum/minimum casting size and weight range?
A Typical products range from 100 grams to 600 kilograms in weight.
-
Q What dimensional accuracy and surface roughness can be achieved?
A Typical dimensional tolerance can reach CT4-8 (Chinese GB standard), and surface roughness can achieve Ra 3.2-6.3 μm, depending on the material and part geometry.
-
Q How do I get a quote? What information is required?
A Please provide part drawings (2D/3D), material specifications, quantity, surface finish requirements, etc. We will provide a quote after a comprehensive process evaluation.
-
Q What is the typical lead time from drawing to finished product?
A Generally 5-8 weeks (depending on part complexity and quantity). Expedited processing is available for prototypes.
-
Q Do you accept small-batch or prototype custom orders?
A Yes, we support small-batch trial production and prototype development, offering technical optimization suggestions to help customers validate design feasibility.
-
Q What types of precision castings do you primarily produce?
A We specialize in investment casting (lost-wax casting). Our materials include carbon steel, alloy steel, stainless steel, aluminum alloys, high-temperature alloys, etc., widely used in construction machinery, automotive, agricultural machinery, hydraulic and other industries.
