Our customized products include internal and external accessories for medium and low-voltage circuit breakers, production and assembly of components, manufacturing of key copper parts, and other custom needs proposed by customers.

If you have 2D/3D drawings, you can provide them directly. If you only have a description of requirements, our engineering team can offer design support: we’ll output solution drawings based on your application scenarios, and start production after confirmation.

Absolutely. Customized products also comply with the ISO 9001 quality management system. From raw material inspection, process control to finished product testing, all follow standardized procedures. Additionally, we add a "special inspection for custom parameters" to ensure they meet your requirements.

The standard process is: requirement communication → solution design → drawing confirmation → sample production → sample acceptance → mass production → delivery. The cycle depends on the product complexity.

Sample costs and lead times depend on the product’s complexity. You can provide drawings or requirement descriptions first, and we’ll evaluate the specific costs and lead times for further discussion.

Yes, but the existing inventory produced before adjustment must be handled. To protect both parties’ interests, there are two options: 1) prioritize using it in subsequent orders; 2) if it can’t be used, we’ll negotiate a reasonable compensation plan.

Custom copper parts typically have a precision of ±0.05mm, sufficient for most electrical connection and conduction scenarios. For surface treatments, we support tin plating, nickel plating, passivation, etc. Plating thickness can be customized based on your needs. Provide detailed usage scenarios or performance indicators, and we’ll recommend the best solution.

Yes. This can be achieved through material selection and process optimization. Please specify environmental parameters in advance, and we’ll design targeted solutions.

We use an MES system to monitor the entire production process of customized products, ensuring consistency and reliability throughout.

Customized product prices are based on materials, process complexity, and order quantity. Without special requirements, the price is similar to standard products.

We accept small-batch custom orders, though pricing may differ from larger orders. Our order quantity requirements are flexible, and we can discuss the right batch size for your project.

Product acceptance is generally based on your requirements, with designs and test reports provided accordingly. If defective products appear during acceptance:If caused by us: free rework or remanufacturing；If not caused by us: a solution will be negotiated.

Yes, we support signing confidentiality agreements and contracts.

We provide a 12-month warranty for our products.

Yes. Long-term customers (with annual purchases ≥ 500,000 RMB) are included in the "VIP Custom Channel" and enjoy benefits such as priority production scheduling, free samples, and 3%-5% discounts on bulk orders.

Yes. We can laser-engrave logos on product surfaces (for copper and plastic parts). Packaging can be custom cartons (with brand information printed) or anti-static bags. Please provide logo specifications and packaging drawings in advance.

We have a comprehensive international technical support system: after receiving feedback, we’ll respond via email within 24 hours, providing multilingual installation manuals, troubleshooting guides, and real-time guidance.

Within the warranty period, if product damage is caused by us, we offer free repair or replacement (you need to provide photos of the problem and third-party test reports). The specific cycle can be negotiated based on your needs. Spare parts are available if required.

We mainly support telegraphic transfer (T/T) payments. If you have other payment method requirements, we’re happy to discuss and find a convenient solution for both parties.

Currently, both sample fees and bulk payments are settled via T/T. This ensures standardized processes and efficient order handling. Thank you for your understanding.

We support multiple shipping methods, chosen entirely based on your needs to fit your logistics plan. You can specify requirements based on order size, delivery time, etc., and we’ll fully cooperate.

Yes, we can arrange shipping via your specified logistics provider (after confirming its service coverage and feasibility). Delivery time is subject to the specified logistics provider. Shipping costs are borne by you, and we’ll fully assist with logistics coordination to ensure smooth delivery.

Please inspect the goods on-site upon receipt. If packaging is damaged or quantity is incorrect, take photos immediately, refuse acceptance, and contact us. If the issue is caused by us, we’ll arrange re-delivery promptly or negotiate a solution.
