When our own conditions and capabilities are insufficient (mainly due to bottlenecks in hardware processing equipment and special processes), we have sufficient upstream and downstream resources to jointly solve the problems, and can professionally and effectively select and manage these Tier 2 (T2) suppliers.

3. We can identify unreasonable aspects of a customer’s design, or situations where subsequent manufacturing processes are difficult to implement (or can be implemented but at excessively high costs leading to waste). For these issues, we can put forward effective suggestions for ID improvements, optimizations, or even design changes, and submit them to the customer for review and confirmation. In fact, numerous customers have benefited from this capability of ours, enabling their projects to be successfully implemented on schedule.

7. FAQs

Q1: Material issue – Does it meet the requirements?

A: Regarding materials, we always provide materials with international standard compositions in accordance with the drawing requirements, and issue material certificates as proof.

Q2: How to ensure the consistency of products during the processing?

A: We can design and manufacture professional tooling for product processing, submit it to the customer for discussion and confirmation, and formulate the processing SOP (Standard Operating Procedure) based on the confirmed tooling to guide production.

Q3: How to ensure the yield rate of products during production?

A: We hold ISO9001 quality management system certification. In strict compliance with the quality system requirements, we implement full closed-loop control over all links in the product processing process, including operators, machinery and equipment, materials, process methods, processing environment (including turnover, placement, and safety), and inspection. We also follow the processes of incoming material inspection, in-process inspection, and outgoing inspection to ensure a 100% yield rate.

Q4: How to ensure on-time delivery with guaranteed quality and quantity?

A: We use production and delivery management software to dynamically display the delivery date required by the order, the arrival time and status of in-transit materials, as well as the completion time and status of each production process.

In case of abnormalities, the software will display corresponding color alerts, and allow uploading of photos of abnormal products and marking the problematic positions on drawings. At the same time, we will immediately arrange for an investigation into the cause: if the issue is related to the customer, we will communicate with them promptly; if it is an internal issue, we will immediately find solutions to resolve it and restore the process to normal (marked in green), ensuring the production process proceeds to the next step.

All processes are traceable, allowing us to identify the specific time node, work team, and even the individual operator involved. All time settings are based on the delivery time we committed to the customer through communication, and we only allow early delivery, not delays. This ensures on-time delivery.

8. Ordering Process

   When engaging and communicating with a customer, we firstly ask the customer to fill out a Customer Requirement Information Form -> The chief engineer convenes personnel from the business, technology, engineering, production, quality, procurement, and PMC (Production and Material Control) departments to evaluate the customer’s products and requirements -> The content of this evaluation meeting will be organized into clear communication points, which the business follow-up specialists use to contact with the customer for discussion and confirmation -> Once we fully understand the customer’s requirements and the customer also fully understands our proposal, and a mutual agreement is reached on technical details, drawings, quantity, quality requirements, and delivery requirements -> we will issue a quotation -> After the customer confirms the quotation, either the customer or we will issue a commercial contract, and both parties will confirm the terms with each other -> Subsequently, the customer issues an official PO (Purchase Order) –> We then initiate the production and delivery process based on the previously confirmed technical document and the PO -> Dynamic confirmation documents are generated during the production process and after completion -> The customer issues an acceptance confirmation form -> Makes payment in accordance with the commercial contract -> Finally, the goods are shipped via logistics.

9. Customer Cooperation Feedback

    All customers provide a feedback form after receiving the goods, which is stored in the project information feedback section. In case of complaints, we will issue an 8D quality improvement report, and the improvement plan confirmed by the customer will also be recorded in the project information. This ensures that when placing a repeat order, the next order can be executed in accordance with the corrected method after improvement.

10. Submit the requirement form

    After communicating with our business staff, if customers decide to choose us and have the intention to cooperate with us, please submit basic information via the requirement form. We will respond and provide feedback within 24 working hours.

Stainless Steel Processing Cases：

1. Food-grade stainless steel products

Project Overview

· Country: Switzerland

· Industry: Food Machinery

· Material: 304 Stainless Steel

· Quantity: 200 pieces/year

· Pain Point: The customer requires that replacing the original non-environmentally friendly brazing process with a welding method, and establishing a single-piece flow lean production supply mode.

Project Challenges

1. Although the value is high, but the quantity is small.

2. Traditional TIG welding (known as argon arc welding in China) causes significant deformation, which leads to imprecise dimensions, and surface polishing is a bottleneck.

Solution

1. Laser welding (without medium) is adopted, which achieves minimal deformation and solves the environmental problem caused by lead in the original brazing process.

2. Sheet metal bending and assembly welding are used to address the challenge of single-piece flow.

3. Parts are pre-polished before welding to overcome the bottleneck of difficult polishing due to structural obstruction.

Project Success

1. The customer was pleasantly surprised to find a suitable process solution that meets almost all the requirements for addressing pain points.

2. The manufacturing process involves mold stretching, sheet metal bending, laser welding, polishing to a mirror finish, and finally electrolytic polishing to produce the finished product.

3. Using the solution provided by Jinzhu, the customer has expanded the application from the original 8 product models to 80 product models with similar structures across the entire group.

The Product Production and Fulfillment Process

1. Communication on Customer Product Drawing Requirements

2. Through laser cutting, mold stretching, CNC machining, bending, rolling (for rounding), TIG/MIG welding, laser welding, grinding and polishing, electrolysis, inspection, packaging, and shipment.

2. Medical-Grade Stainless Steel Products

American Stainless Steel Medical Device Customer (Ranked Top 3 in the Industry)

Project Overview

· Country: USA (a top 3 company in the medical device industry)

· Industry: Medical Devices (consumables, disposable—discarded after use and re-ordered for replenishment)

· Material: 316 Stainless Steel

· Quantity: Four types of products, with the quantity of each product exceeding 10,000 units.

· Value: The total order value of the four products is approximately 20 million RMB.

· Process Requirements: Mold forming + precision machining + precision laser welding (micro-deformation) + polishing + cleaning + inspection

· Pain Points:

Ø Medical devices have extremely high requirements; production is to be carried out in China, while certification is completed by the customer in the USA (certification has already been obtained);

Ø It is difficult to find manufacturers capable of precision laser welding;

Ø Professional cleaning conditions and sterile packaging are required;

Ø Professional optical inspection equipment is required.

Project Challenges

1. There are no issues with processing or welding (laser welding).

2. Cleaning and inspection are feasible.

Solution

Laser welding (without medium) is adopted, which results in minimal deformation. Basically, laser welding is universally used in medical devices.

Summary：

production process：

A: Laser cutting processing

B: CNC bending processing

C: CNC stamping processing

D: CNC rolling (rounding) processing

E: TIG/MIG welding processing

F: Laser welding processing

J: Grinding and polishing, spraying or electrolytic polishing, assembly

There are a total of seven processes, namely A, B, C, D, E, F, and J. These seven processes:

1. Each individual process can be independently formed into an order;

2. An order can also be formed by combining any two or three of these processes;

3. Additionally, there are cases where customers need all seven services to form an order;

4. There is another scenario: when a customer has secured six of these processes but only cannot find a provider for laser welding, they will also come to us. They may even request their existing suppliers to designate us for the laser welding service—this is because neither the customer nor their suppliers have found a laser welding partner in the market that delivers better results than we do.

5. During communication and cooperation, since laser welding technology is crucial yet relatively niche, customers may sometimes ask us - Jinzhu, to act as the primary supplier to undertake the order. This allows us to coordinate with other secondary suppliers (who offer common services easily available in the market) to support our operations.

After we assembled the Technical Department, Engineering Department, Production Department, Quality Department, PMC (Production Material Control), Purchasing Department, and Packaging Department for a meeting to discuss and evaluate, we provided the following processing flow to the customer for confirmation. After communication, optimization, adjustment, and revision, a solution that both parties fully understand was finally formed as follows:

After receiving this solution, the U.S. customer's various departments highly recognized and were satisfied with our approach and the feasible solution which we proposed, and subsequently placed a purchase order (PO) with us for 40 sets.

Case 2:

In September 2025, for the constant-temperature incubator used for biological strain cultivation in the United States (material: 316 stainless steel), the processes included mold stretching, sandblasting, electrolysis, and laser welding of screws. The requirement was to perform welding on the back with no traces left on the front.Previously, the customer used spot welding for screw planting, which resulted in large weld marks on the front. We solved the problems of residual traces and convex bumps by adopting precision laser welding.

The physical photos of the products we processed and manufactured are as follows：

Case 3：

Since September 2023, we have been collaborating with a U.S. customer on stainless steel medical automatic cleaning and disinfection carts. The project involves 54 sets of stamping and stretching molds, ultra-thin 316 stainless steel materials, precision assembly welding, passivation, and packaging for air shipment. This project aims to replace all plastic products used in the past 20 years with stainless steel alternatives, with an annual replacement volume of 5,000 units.
