Custom Metal Parts FAQ
-
Q : What types of engineering or design support do you offer?
A : We do not design complete products. But nineteen engineers review manufacturability before tooling starts. They advise on materials and processes to cut cost and risk. Design for manufacturing feedback is free. Material options are compared honestly. Process suggestions reduce waste. Send drawings even if the design is rough. You will get useful feedback with your quote.
-
Q : Can you handle small batches and high-volume orders?
A : Yes. Projects range from a few simple brackets to 500,000 pieces per month. Each order gets a capacity check before we confirm delivery. Prototype runs test the design. Low-volume runs share standard tooling. High-volume runs reserve press time. Our monthly capacity exceeds 500,000 pieces. Send your drawings and target volume for a straight answer.
-
Q : Is it possible to obtain metal parts without scratches?
A : Yes. Aluminum and stainless steel can carry removable protective film. Clean handling and separated trays protect finished surfaces. Cosmetic parts arrive ready to use. Film is applied right after finishing. Gloves prevent fingerprints. Trays and partitions stop part contact. Request surface protection when you place your order. Tell us your cosmetic standard.
-
Q : How thick a metal can you process?
A : Stamping limits depend on material grade. Stainless steel goes up to 3.2 mm. Low-carbon steel reaches 4.2 mm. Aluminum goes up to 3.6 mm. Laser cutting handles thicker material. Stainless steel cuts up to 28.5 mm. Low-carbon steel reaches 25.4 mm. Aluminum matches 28.5 mm. Larger parts may reduce maximum thickness. Hardness changes press limits.

-
Q : Which materials do you process?
A : We process carbon steel, aluminum, stainless steel and titanium. Many other metals are available on request. Material certificates confirm grade and source. Stainless steel: 304, 316 and 430 common. Aluminum: forming and finishing friendly. Carbon steel: strong and cost-effective. Tell us your material and application. Our engineers will confirm supply and process within 8 hours.
-
Q : How do we select the appropriate steel type for your sheet metal parts?
A : We mainly use three commercial stainless steel grades. 316 resists corrosion best and suits marine use. 304 fits most indoor and food-contact parts. 430 offers a low-cost, magnetic option. 316: coastal, chemical and medical environments. 304: general and food-contact applications. 430: cost-sensitive, less corrosive environments. All three grades can be welded and finished. Read our full stainless steel material guide for comparisons. Unsure which grade fits? Send your drawings for a material recommendation.
-
Q : What types of metal parts have you produced?
A : We manufacture many custom metal parts. Examples include metal clips, box body shells, trays, supports, frames and hardware tools. Since 1999, over 70,000 full-process projects have left our factory. Stamped and drawn parts up to press limits. Welded frames and enclosures. Finished parts with plating or powder coating. Browse our case presentations to see real projects.
-
Q : Which custom metal fabrication services do you offer?
A : We offer stamping and forming, cutting and blanking, welding and joining, CNC machining, surface treatment and casting. Design optimization supports every step. Stamping and deep drawing for volume parts. Laser cutting for complex shapes. CNC machining for tight features. Casting for three-dimensional parts. Each service page shows details.

-
Q : Which industries have you supplied before?
A : Our Nanpi production base has supplied many industries since 1999. Healthcare, food service, semiconductors, electronics, transportation and industrial equipment lead the list. Medical parts demand clean and traceable production. Electronics parts need tight tolerances. Industrial parts combine forming and welding. Quality expectations stay high everywhere.
