Slotted quartz rod with circular holes is a high-end quartz product widely used in precision industry and scientific research. It achieves precise guidance and control of light, fluid, gas, or mechanical positioning by opening specific grooves and circular hole structures on the surface of the quartz rod.

FAQ: The four core issues that users are most concerned about

1. What practical problems can slot and circular hole structures solve?  

It can accurately control the flow direction of liquids or gases, achieve the fixation and guidance of optical paths, or complete mechanical positioning and limiting during assembly, avoiding the accumulation of errors when multiple components are matched.

2. Is it suitable for high temperature or corrosive environments?  

Yes, it is. Quartz material is resistant to high temperatures (up to 1100 ℃ for long-term use), strong acids and alkalis, and has an extremely low coefficient of thermal expansion. It is suitable for harsh working conditions such as semiconductors, optical communications, and chemical experiments.

3. Can we customize specifications based on the structure of our equipment?  

Okay. We provide full-size customization of outer diameter, length, groove width, groove depth, circular hole diameter, hole position distribution, and end face shape, with a minimum aperture of 0.5mm and a tolerance controlled within ± 0.02mm.

What is the supply cycle and minimum order quantity?  

The regular customization cycle is around 7-12 working days, with no strict minimum order quantity limit, supporting single piece trial production and small batch rapid delivery.

Customer Application Case (Anonymous)

Case 1: A European optical communication module manufacturer

Demand

The customer needs to use a quartz rod in a high-density wavelength division multiplexing module to simultaneously achieve physical positioning of the fiber array and guidance of the optical path coupling medium. Require two parallel V-shaped grooves and three vertical circular holes with a diameter of 0.8mm on the surface of the rod, with a positional accuracy of ± 0.01mm and a surface roughness Ra ≤ 0.4 μ m.

Solution

We use high-purity fused silica bar, through the combination of precision grinding and laser drilling process, first form the V-shaped groove, and then use laser vertical drilling to ensure that the relative position between the groove bottom and the hole center does not shift. The product undergoes a 100 fold microscope inspection and air tightness test before leaving the factory.

Final effect

After customer assembly, the fiber coupling efficiency increased by 12%, the assembly time was shortened by 30%, and the batch yield rate increased from 92% to 98.5%.

Case 2: Gas distribution components for cavity of domestic semiconductor equipment enterprises

Demand

The quartz rod used for gas distribution in the reaction chamber of the etching equipment needs to be uniformly distributed with 6 sets of intersecting circular holes along the axial direction, forming a gas buffer channel between the holes and grooves. It is required to be resistant to CF ₄ plasma corrosion and not deform at a long-term operating temperature of 200 ℃.

Solution

We adopt a secondary heat setting process, first rough machining the slot structure, then high-temperature annealing to eliminate processing stress, and finally precision grinding to the final size. All holes should be chamfered to avoid discharge accumulation.

Final effect

The components have been running continuously on the customer's machine for 5000 hours without deformation or particle shedding, and the gas uniformity index is better than the original imported components. The customer has switched all similar components to be supplied by us.
