As a true high performance glass sphere balls manufacturing factory, Hengyuan employs a five-step precision process:

Step 1: Material selection – Soda lime, borosilicate, black glass, or quartz rods are cut to preforms.
Step 2: Rough grinding – Achieve near-net shape using coarse abrasives.
Step 3: Fine grinding – Reduce sphericity error using lapping plates.
Step 4: Precision polishing – Damping cloth and sub-micron polishing powders to achieve roughness <2nm Ra and surface quality 10/5.
Step 5: 100% inspection – Digital micrometer, lever micrometer, and roundness instrument verify diameter tolerance per batch and sphericity.

This process allows us to deliver high-precision glass balls with excellent durability, high dimensional stability, and lower deformation under load.

Beyond standard precision glass balls, Hengyuan is one of the few high performance glass sphere balls manufacturing factory that also produces preform balls for molded aspherical lenses. These preforms are used by leading optics companies in cameras, automotive LiDAR, and AR/VR headsets.

To help you specify the correct product from a high performance glass sphere balls manufacturing factory, consider these five factors:

Grade 3-10: For ultra-high precision applications like medical devices, aerospace sensors, and optical assemblies.
Grade 25-100: For general industrial flow meters, check valves, and instrumentation.
Grade 200-1000: For less critical applications such as cosmetic roll-ons, decorative uses, or bearing filler balls.

High temperature (>200°C): Choose borosilicate or quartz glass.
Strong acids/chemicals: Borosilicate glass provides very high chemical resistance.
Alkaline solutions: Soda lime glass is more resistant to high alkaline environments.
Opacity requirement: Black glass is ideal to prevent light transmission.

Hengyuan offers diameters from 0.60mm to 150mm. For diameters below 1mm, tighter tolerances are achievable. Always specify diameter tolerance per unit container and single ball diameter tolerance.

For medical or semiconductor use, request cleanroom Class 10,000 packaging with clean vacuum plastic bags or clean waffle trays. Standard packaging is suitable for most industrial uses.

Every batch from Hengyuan includes a certificate of conformance showing measured sphericity, diameter tolerance per batch, surface roughness, and material composition.
