FAQ
1. Question: What file formats of design drawings can you handle? What suggestions do you have for design?
Answer: We support mainstream 2D and 3D file formats such as. dwg,. dxf,. step,. igs, etc. To ensure accurate pricing and smooth production, we recommend that you specify all key dimensions, tolerance requirements, material specifications, and expected surface treatments in the design. Our engineers can also provide you with design optimization suggestions to improve manufacturability and cost-effectiveness.
2. Question: How long does it take from receiving the drawings to obtaining the quotation? How long is the production cycle usually?
Answer: For drawings with standard complexity, we usually provide detailed quotations within 1-3 working days. The production cycle depends on the complexity and quantity of the order. Generally speaking, it takes 5-10 working days for sample parts and 2-4 weeks for small and medium batch production. For urgent orders, we can provide expedited services, and the specific plan needs to be discussed and confirmed.
3. Question: How do you ensure product quality, especially during mass production?
Answer: We implement a full process quality management system:
Incoming inspection: Ensure that all board materials and thicknesses meet the standards.
Process inspection: Conduct first piece inspection and sampling inspection in key processes such as laser cutting, bending, and welding.
Factory inspection: Conduct 100% size, appearance, and functional checks on the finished product to ensure consistency with your sample or standard.
We promise to deliver every batch of products to you with high consistency and perfect quality.
4. Question: How to choose the appropriate material and surface treatment for stainless steel casing?
Answer:
Material selection:
304 stainless steel: suitable for most daily and industrial environments, with good corrosion resistance and formability.
316 stainless steel: recommended for use in maritime, chemical, or high humidity environments, with stronger resistance to chloride corrosion.
430 stainless steel: suitable for indoor environments that are dry and do not require high corrosion resistance, with high cost-effectiveness.
Surface treatment selection:
Brushed/frosted: Elegant appearance, wear-resistant, and can effectively hide subtle scratches.
Mirror polishing: presenting high glossiness, highlighting the high-end positioning of the product.
Sandblasting: creates a matte texture, with a delicate touch and anti fingerprint properties.
Electroplating/PVD: Provides colors such as black, gold, and gun colors, greatly improving aesthetics and wear resistance.
Our sales engineers can recommend the best solution for you based on your specific application scenario and budget.
5. Question: Do you process other materials besides stainless steel? What is the minimum order quantity?
Answer: Yes, in addition to various types of stainless steel, we also process other metal sheets such as cold-rolled sheets, galvanized sheets, aluminum sheets, brass, etc. Regarding the minimum order quantity, we are very flexible and can provide small batch or even single piece sampling services for the R&D stage. At the same time, we also support subsequent large-scale production to meet your needs throughout the entire stage from prototype verification to market launch.
