We offer in-house mold design, production, and rapid prototyping services, helping clients accelerate development timelines and reduce costs.

(3) CNC Machining Services:
Our high-precision CNC milling, CNC Turning, EDM and CNC lathe machining services allow us to meet strict tolerance requirements, ensuring parts are finished to exact specifications.

(4) Heat Treatment Services:
We provide complete heat treatment solutions, including quenching, annealing, tempering, normalizing, aging, carburizing and nitriding to enhance material strength, hardness, and durability.

(5) Surface Treatment Services:
We offer polishing, blackening, electroplating, electrophoresis, powder coating and other treatments to improve the corrosion resistance, wear resistance, and aesthetic appearance of products.

Material: A3 Steel

Challenge / Problem:
1. The initial design of the product was to cast it as a whole. Since the wrench handle is relatively long, it is difficult to shape it.
2. The surface of the product is copper-plated and then chrome-plated, which magnifies the surface defects of the product, resulting in a high rework rate and an increase in the scrap rate.

Solution:
1. Divide the product into two sections, cast the wrench head part, and use processed steel plates for the wrench handle.
2. Connect them together by welding, which does not affect the performance of the product.

Results & Impact:
The product has a better appearance and texture, and reduced the cost by about 50%, which has achieved customer satisfaction and won customer trust.

Material: 304 Stainless Steel

Challenge / Problem:
1. The product has curved small holes connected inside, which makes it difficult to build the mold.
2. Shell making and subsequent sand cleaning during casting are difficult, resulting in a high scrap rate.

Solution:
We use sand cores with good high temperature strength inside the product, which are easy to clean after high temperature, and solve the casting problem of the curved hole part very well.

Results & Impact:
The product’s performance improved significantly, rework rates decreased, and delivery time was shortened. This earned customer trust and led to a long-term partnership.

Material: 316 Stainless Steel

Challenge / Problem:
1. The product has a small opening and a complex inner cavity, making it almost impossible to produce.
2. It is difficult to clean the sand inside the product.

Solution:
1. Open a square hole on the back of the product, use a stainless steel square plate for welding, and design a dovetail groove at the weld to improve the firmness of the weld.
2. Used high-temperature-resistant, high-strength sand cores internally, ensuring air tightness requirements were met.

Results & Impact:
The product became more cost-effective, efficiency improved, and its performance in applications was enhanced, earning customer trust.

Material: 316 Stainless Steel

Challenge / Problem:
1. The product structure is complex and the mold cannot be made as a whole.
2. The product has high verticality requirements.

Solution:
1. Connected the upper and lower wax molds and used aluminum tooling blocks during the wax mold process for alignment.
2. After the product is formed, we use tooling to shape it and use a checking fixture to check the verticality.

Results & Impact:
The performance and appearance of the product have been recognized by customers and a long-term cooperative relationship has been established.
