Machining Equipmnet
Horizontal Lathe:
The maximum workpiece rotation diameter for machining is Ø 1600mm, the maximum workpiece rotation diameter for tool holder is Ø 1250mm, and the maximum workpiece length is 6m.
CNC vertical lathe:
With a maximum processing capacity of Ø 1600mm. It mainly processes large disc and cover parts. Such as the outer circle, inner hole, internal thread, external thread, sealing gear, etc. of the end face of the piston/gland.
External grinding machine:
The external grinding accuracy is IT5-IT6, the roughness is Ra 0.1-0.4, the grinding diameter is Ф 800mm, and the grinding length is within 6m.
Deep hole boring/scraping rolling machine:
It is mainly used for machining inner holes in cylinder bodies, with the ability to machine inner holes with the diameter of less than Ф 630mm and the length of less than 6m.
Every piece of hydraulic cylinder are processed through dozens of steps, including raw material processing, cylinder assembly, painting, etc. Each step is indispensable, and we also have advanced processing equipment to ensure that the processing dimensions of raw materials meet the requirements of product production.
Quality Inspection
Raw Material Inspection:
The material of raw materials is detected by carbon and sulfur analyzers and spectrometers.
Material Performance Inspection:
The tensile strength, yield strength, hardness and other properties of the material are tested by the material tensile test bench,Brinell hardness tester, Vickers hardness tester and other equipment.
Process Inspection:
The geometric shape, shape and position tolerance and finish of semi-finished products are detected by three coordinates,
profilometer and ultrasonic roughness meter.
Chrome Plating Control:
The thickness, hardness and corrosion resistance of the product coating are tested by ultrasonic hardness tester, ultrasonic thickness gauge and salt spray test bench.
Every piece of hydraulic cylinder are tested and will send out only after they are pasted the each test. Our company has abundant technical force and perfect testing means. By making wide technical and business cooperation with many related enterprises, universities, colleges and institutes both at home and abroad, and employing senior engineers and software engineers, we have greatly strengthened and improved our designing, processing, and testing abilities.

FAQ
Q1. What are the same aspects of your cylinder with Hyva cylinder?
A: Same inside structure.
Same outside dimension and same mounting sizes. It can be interchangeable with Hyva's
Q2. Compared with Hyva cylinder, what are your cylinder advantages?
A: 1. Rod are chrome plated.
2. Tubes are quenched and tempered.
3. Tube inner hole goes through deep hole boring machine processing. Surface roughness is 0.4Ra and circular degree is 0.025.
4. Good quality yet lower price.
Q3: Are you a manufacture or a trade company?
A: Manufacture, we are the leader manufacturer of hydraulic industry in China with over 20 years' experience and technology accumulation. With strong technical team we could solve any annoyance of you.
Q4: Do you have quality control system?
A: Yes, The quality management system introduced is: ISO/TS 16949:2009-certified by NQA and IATF cert.
Q5: How can I get a booklet and buy a cylinder from you?
A: Very easy! Just leave me a message or email or call me directly, let me know you are interesting in our products. I will talk with you for the details soon!
Q6: Can you tell me the price for the cylinder?
A: 1. Please advice the drawing with technical requirement.
2. Please advice the model No. after you check our booklet.
3. Please advice the tipping capacity, number of stages, closed length, mounting type and size.
4. Please also help advice the quantities, this is very important.
Q7: Do your products come with a warranty?
A: Yes, we have 14 months from production time. In this time, if the quality problem we will free repair for you.
Q8: Hydraulic cylinder internal leakage?
A: 3 main reasons causing internal leakage: overload, polishing bad controlled, cheap seal kits.
