Silicon carbide nanoscale coating technology

Heifeiling is committed to providing customers with the most effective graphite solutions to meet their most challenging needs. We can independently recommend the best and most economical graphite grade for your application.


When developing our own materials, Heifeiling cooperates closely with universities and research institutes. Heifeiling Graphite is constantly redefining boundaries through continuous testing, grade formulation and purification to develop innovative graphite material solutions for customers in more than 30 countries.

Processing technology

Difficult processing

Other processing

Thin wall machining

We can successfully complete challenging thin-walled machining jobs by optimizing fixtures and machining methods.

3D processing

We prepare 3D models according to drawings and write programs to manufacture the required products. Upon request, we can also measure the actual product and produce the product to actual size.

Special inner diameter processing

We can perform special ID machining jobs to create solid parts without cutting the workpiece into segments.

Manufacture of larger parts

Large rings, pipes, chimneys, pedestals and andands are made from smaller parts. This unique trapezoidal design eliminates the need for large diameter feeders that typically require long lead times.

Sectional processing

We can perform complex machining tasks such as ensuring that there are no gaps between mating surfaces (no light leakage), which is required for segmented products used in compressor piston rings and similar applications.

Porous materials

We are capable of fast precision machining of very demanding porous objects.

INSPECTION AND QUALITY CONTROL

Haifeiling has passed ISO9001:2015 certification, and our graphite products have been tested according to international, national and industrial standards. The equipment has a three-coordinate measuring instrument with an accuracy up to 0.02mm, a bending resistance, compression resistance and Shaoshi hardness tester. The company actively builds an enterprise quality management system and conducts comprehensive quality inspections. It has four functions: Gatekeeper, Prevention, Reporting and Improvement. Commonly used test standards are as follows:

● Dimensional inspection: According to customer drawing requirements or national standard tolerance table

● Shore hardness testing

● Flexural strength test

● Quantity

● Filler

● Weight

● Component
