Application

 

Copper balls are used in galvanic applications and in the field of electronic industry.

 

 

OEM

 

Because we're not just a ball company, we can go beyond this technology to provide subassemblies or complete solutions. We can combine our ball technology with our injection molding, segmented linear bearing, and motion control expertise. We have extensive in-house tool room capabilities and offer rapid prototyping. With manufacturing facilities that span the globe, we can produce and deliver your solution with minimum time and cost.

 

Distinctively Shaped Ball: We offer a variety of flat, diagonally cut, cone and pin shaped balls that are typically used as hardened polishing and shaping tools. For example, the diagonally cut and shaped balls can be used to polish surfaces with sharp angles. Flat balls are typically used to polish uniformly shaped surfaces such as soins. Sizes and materials can be made available to suit your needs. Contact us to find the product that's just right for you.

 

Drilled Ball: Mingliang offers a full range of sizes, hole depths (including thru-hole), diameters and materials. Typical applications include body jewelry, earring posts, rings, seal slides, valves, and automotive engine push rods.

 

Plated Ball: Platings are used to enhance the physical properties of precision balls. These may include added hardness (titanium nitride), corrosion resistance (molybdenum disulfide), noise supression (rubber), and electrical characteristics (gold). Mingliang offers a myriad of plating to meet your needs.

 

Hollow Ball: Hollow balls are typically used for weight sensitive applications such as aircraft ball transfer units, liquid float systems, and custom ball valves. We provide 201, 304, 316 stainless steel hollow balls in a variety of sizes.

Production Flow

 

Heading: A coil of wire is cut to the required length and each piece compressed and shaped into balls using a pressing machine.
 
Flashing: The surface of the balls is ground to remove the bands generated in the heading process.
 
Heat treatment: After the bands have been removed, the balls are quenched adn tempered to give them sufficient strength and durability.
 
Grinding: In addition to removing parts decarburized in the heat treatment, this process adjusts dimensional precision and finishes the balls to the stipulated dimensional difference.
 
First lapping: The dimensional precision of the balls is further improved and they are finished to the specified dimensional difference.
 
Second lapping: In addition to increasing the balls' dimensional precision to grade level, this process gives the surface of the balls a smooth, glass like finish.
 
Visual inspection: All of the finished steel balls and all of their surface visually inspected automatically. These visual inspection ensure that the balls supplied to customers have no flaws.
 
Packing: Balls that pass visual inspection are treated with anti-corrosive oil and then packed in paperboard boxes.

 

 

 

Quality Assurance

 

After precision washing, oiling & before packing sample balls from the batch are sent for final audit to check for surface roughness, roundness, waviness, lot size variation and hardness in a sophisticated laboratory, according to specified control plans and dock audit procedures. Once all requirements are met, a test certificate is then prepared for the customer. Our sophisticated laboratory is equipped with high precision, worldwide respected machines and equipment and is managed by properly trained and qualified personnel.
