FAQS
Yes. We offer customized packaging and labeling services based on your requirements. Options include individual packaging, protective foam, custom cartons, export-grade wooden crates, barcode labels, part number labels, and customer-specific packaging to ensure safe transportation and efficient inventory management.
Yes. We can provide various inspection documents upon request, including First Article Inspection (FAI) reports, dimensional inspection reports, material certificates, Certificates of Conformance (CoC), and other quality documentation to support your project and compliance requirements.
We use a wide range of precision inspection equipment, including Coordinate Measuring Machines (CMM), digital calipers, micrometers, height gauges, thread gauges, pin gauges, bore gauges, and other measuring instruments. Our inspection process ensures that every component meets the required dimensional and quality standards.
Yes. We provide hardware installation services as part of our assembly process. We can install screws, nuts, bolts, threaded inserts, rivets, PEM fasteners, standoffs, pins, and other standard hardware according to your drawings and assembly specifications, ensuring secure and accurate installation.
Vacuum casting silicone molds are typically completed within 5–10 business days, allowing rapid prototype production. Die casting steel molds usually require 3–6 weeks, depending on part complexity and tooling requirements. We will provide an estimated tooling schedule with every quotation.
We offer a range of die casting materials, including aluminum alloys, zinc alloys, and magnesium alloys. Aluminum is widely used for its strength, lightweight properties, and corrosion resistance. Zinc provides excellent dimensional accuracy and is suitable for small, intricate components, while magnesium offers an outstanding strength-to-weight ratio for lightweight applications.
The best casting process depends on your production volume, material, and product requirements. Die casting is recommended for medium- to high-volume production of metal parts that require excellent strength and dimensional consistency. Vacuum casting is ideal for rapid prototyping and low-volume production of plastic parts with high-quality surface finishes. Our engineering team can help you select the most suitable process based on your project goals.
Die casting is a high-volume manufacturing process that injects molten metal into a hardened steel mold under high pressure. It is ideal for producing durable, high-precision metal parts with excellent repeatability. Vacuum casting uses silicone molds to produce plastic or rubber-like parts, making it a cost-effective solution for prototypes and low-volume production. The right process depends on your material, quantity, budget, and application requirements.
Anodizing is an electrochemical process that creates a durable oxide layer on the surface of aluminum, improving corrosion resistance, wear resistance, and hardness while maintaining a metallic appearance. Powder coating applies a protective polymer coating that provides excellent durability, impact resistance, and a wide range of color options. Anodizing is suitable only for aluminum, while powder coating can be applied to aluminum, steel, and other metals. The best choice depends on your application, performance requirements, and desired appearance.
Yes. We offer anodizing in a variety of standard colors, including clear (natural), black, red, blue, gold, and other custom colors, depending on the material and project requirements. Anodizing not only enhances the appearance of aluminum parts but also improves corrosion resistance, wear resistance, and surface hardness. If you have specific color requirements, we can match them as closely as possible.
The best surface finish depends on your application, material, operating environment, and appearance requirements. For example, anodizing improves corrosion resistance for aluminum, powder coating provides a durable decorative finish, while plating enhances wear resistance and electrical conductivity. Our engineering team can recommend the most suitable finishing process based on your functional and aesthetic requirements.
Yes. We offer a variety of RoHS-compliant surface finishing options, including anodizing, powder coating, passivation, zinc plating, electroless nickel plating, and other environmentally compliant treatments. If your project requires RoHS, REACH, or other regulatory compliance, please let us know during the quotation stage.
Surface finish quality is inspected through visual examination, dimensional verification, and process-specific quality checks. We evaluate appearance, coating uniformity, color consistency, adhesion, and surface defects. When required, we also verify surface roughness and coating thickness using professional inspection equipment to ensure compliance with customer specifications.
Some surface finishing processes can slightly affect part dimensions by adding or removing a thin layer of material. Processes such as anodizing, plating, and powder coating may change surface thickness, while polishing can remove a small amount of material. If your project has critical tolerances, our engineering team will consider the finishing process during manufacturing to ensure the final part meets your specifications.
Yes. We understand the importance of protecting your intellectual property. We are happy to sign a Non-Disclosure Agreement (NDA) before reviewing your drawings or project information. All customer data is handled with strict confidentiality throughout the entire manufacturing process.
All parts are carefully inspected and securely packaged before shipment. Depending on the product type, we use protective wrapping, foam inserts, individual bags, custom cartons, and export-grade wooden crates to ensure the parts arrive safely and in excellent condition.
