Directly address the pain points of custom processing of non-standard equipment

When many companies engage in the production of non-standard equipment, finding suppliers is a huge headache. If you look for a small processing factory, the equipment will lack precision and cannot even process large parts; if you look for a larger enterprise, you will face a situation of high minimum order quantity, long delivery time, and unsatisfactory service. After the parts are completed, there will be deviations in size, rough surfaces, and deformation during welding. Rework will not only delay the construction period, but also increase costs.

We are committed to solving such difficulties. As a company with large-scale equipment such as 3-meter, 4-meter, and 6-meter four-axis linkage CNC gantry milling, CNC floor boring, CNC vertical lathe, etc., we are able to achieve full process control from drawings to finished products. In 2025, we processed the mining crusher box for a heavy industry enterprise in Shandong. The dimensional error was controlled within 0.02 mm, and the welded parts that were integrally annealed did not show any deformation.

Pay equal attention to precision and efficiency in blanking medium and thick plates

Cutting off medium-thick plates is the first critical procedure in mechanical processing. Many customers have reported that if the dimensions of the blanks are inaccurate, it will cause position deviation during subsequent riveting and welding assembly, and even cause the entire structural part to be scrapped. In the blanking process, we use CNC plasma and laser cutting equipment to accurately blank medium-thick plates from 16 mm to 80 mm. Non-standard welding parts processing, external processing of welding parts, and custom processing of Q235 thick steel plate bending and welding make the cutting surface smooth and do not need to be polished again.

Taking the petrochemical spare parts project completed in March 2026 as an example, the customer has needs and needs 30 steel plates with a thickness of 40 mm to be used as welding bases. We use CNC programming to complete the blanking at one time, and the dimensional tolerance is controlled to ±0.5 mm. Compared with traditional flame cutting, the efficiency is increased by 40%, and the material utilization rate is as high as 92%.

Quality assurance of riveted and welded customized structural parts

When joining various components of non-standard equipment, riveting is a key process. Once the welding quality does not meet the requirements, cracks, pores, and slag inclusions will occur, causing the equipment to break during use. We have an experienced welding team, qualified in pressure vessel and steel structure welding, and can weld high-strength steel, stainless steel, wear-resistant plates and other materials.

We carry out pre-treatment work both before and after welding. For example, for the gear box weldments produced for a mining company at the end of 2025, we chose carbon dioxide gas shielded welding. After completing the welding, annealing was performed to eliminate stress, and then it was handed over to CNC gantry milling for finishing. In the end, the flatness of the entire cabinet reached 0.03 mm. When the customer accepted it, he was extremely satisfied.

Full coverage of large-scale CNC equipment processing range

Our workshop is equipped with non-standard equipment for cutting and welding of medium-thick plates . There are various specifications of 3 meters, 4 meters and 6 meters. CNC gantry milling and custom-made equipment for cutting and welding of medium-thick plates are equipped with four-axis linkage operation mode. They all have milling heads specially used for side processing, which can process large parts with a length of 6 meters and a width of 3 meters. As for CNC floor boring, it has the ability to process high-precision hole systems. CNC vertical lathe can process rotary parts with a diameter of up to 5 meters. CNC horizontal lathe can process long-axis parts.

These equipment are suitable for processing large-module gears, boxes, shaft parts, molds and other special-shaped workpieces. In April 2026, we processed a set of mold steel modules weighing 15 tons for an automobile mold factory. After a single clamping process of 6-meter gantry milling, all profile dimensions were qualified at once, saving the customer at least three days of manual grinding time.

One-stop service from raw materials to finished products

Many machining companies can only engage in machining, and customers must coordinate the procurement of raw materials and subsequent assembly themselves. We provide one-stop services starting from raw material procurement, including blanking, welding, heat treatment, rough machining, finishing and assembly. Customers only need to provide drawings and requirements.

We have maintained long-term cooperative relationships with many large local steel mills and are able to obtain steel plates, forgings and castings with high quality and favorable prices. In May 2026, a chemical equipment company from Guangdong urgently needed 8 sets of non-standard mixers. It only took 15 days from the confirmation of the drawings to the delivery of the finished products. This is because we directly purchase Q345R steel plates, weld them immediately after cutting them, then go to the lathe to fine-turn the shaft end, and finally conduct assembly testing. There is no outsourcing in the entire process.

Non-standard equipment manufacturing case data speaks

Producing a complete set of spare parts for mining crushers is a challenge for non-standard equipment manufacturing that greatly tests the company's comprehensive supporting capabilities. In 2025, we produced a complete set of spare parts for the mining crusher for the cement factory in Hebei, including ring gears, main shafts, hammer heads, and screen plates. The number reached more than 120 pieces, and the cumulative total weight exceeded 80 tons. From the time the steel castings were returned to the factory to the completion of assembly, it only took us 28 days to complete the entire process.

We provide you with a rewritten sentence that uses complex sentence structures and uncommon vocabulary: Each part is carefully processed by CNC machine tools. The tooth surface hardness of the gear reaches HRC58-62. After the spindle is quenched and tempered, its tensile strength reaches 900 MPa. Customer feedback shows that after one year of operation of the equipment, the wear and tear of the main components is still within a reasonable range, and no abnormal failures have occurred. This is the performance of our strength with excellent equipment, exquisite craftsmanship and excellent team.

What are the non-standard parts that you urgently need to process at the moment? Is it a large gear shaft, a box, or a welded piece of non-standard equipment, thick plate blanking and riveting customization , or a mold or complete set of equipment? You are welcome to leave a trace in the comment area. After that, we will provide a professional processing plan and quotation based on the drawings and needs you provided.
