Yantai Haige International Trading Co.,Ltd., is a joint-stock enterprise engaged in exporting niche mechanical equipment produced in China to the markets abroad, which is located in Laishan district, Yantai City, Shandong Province, China.

    The company is based on the manufacturing plant---Yantai Haige machine tools Co.,Ltd & Yantai Hangjian Refined Special Steel Equipment Co.,Ltd. whose area is more than 70000m2. There are one hundred and forty staffs working in the factory. The factory is mainly engaged in producing and selling bar peeling machines(centerless lathes), straightening machines, polishing machines(abrasive belt machines), auxiliary machines and other processing and finishing equipment for steel(bright steel) for more than ten years.

 from Outside the Factory

    Our company has strong R&D and production capacity. Equipped with specialized R&D center whose R&D capacity, software and hardware configuration, and the staff size all rank first in this field.  Keeping in step with the latest international technology, the R&D center develops the new equipment and upgrades the existing ones that provides a solid technical support and guarantee for our machines to keep technology leadership all the time.With advanced technology, high quality, high precision, high reliability, high efficiency,automatic line process and excellent after-sale service,our metal finishing equipment in full sets not only have been sold well to nearly thirty domestic provinces, cities, and autonomous regions, but also spread to Russia, Korea, India, Vietnam, North Korea, Pakistan, Taiwan, etc.

 from Inside the Factory

    Our company regards quality of products as the life. It has passed and strictly enforced the ISO9001 international quality system certification.Depending on strong software&hardware facilities and strict quality control, the company has passed the inspection and acceptance of the State Administration for Entry-Exit Inspection and Quarantine Bureau and won the centerless lathe " Export Quality License" as well as straightening machine " Export  Quality License".

    JY Series of straightening machine can realized precise straightening and polishing on the after peeling or grinding metal bar surface utilizing the special curves and angles between the top and bottom two rollers. It can be used in black bar material straightening as well.
There are 3 types of structure in straightening machine, two beam four column structure, prestressed structure and frame structure.The straightness can be up to 0.15——0.4mm/m , and the roughness Ra<1μm after straightening.

straightening roller:

For two-rolls straightening machine, the bending moment of raw material is realized by concave roll. Another advantage is that the angle between rolls angle and rod axis is small, whiche is 15^°. So the screw pitch of envelop line is shorter, and its straightness accuracy is higher.

Application: It could be used for bright bar , and black bar with suitable bending and surface hardness .Its straightening speed is slower than multi-rolls straightener, but its straightness accuracy is higher ,and its cost is lower.

Advantages compared with the general lathe

1. The over-long metal bars or the wire rods can also be processed.

2. The precessing speed: 1~12m/min which is several times faster than the general lathe.

3. High precision. The diameter tolerance  ≤IT9 while the surface roughness ≤6.3μm after peeling.

   The surface roughness can be less than 0.8μm if our straightening machines are used afterward.

Loader→Uncoil machine→Centerless lathe→Cutting machine→Charging basket

    We have rich experience in export packaging with professional packaging and professional packing staff. Multilayer packaging is adopted with critical area wrapped with moisture proof and shock proof film, plywood box, or wood box and tray. Multiple reinforcement measures is applied to ensure the solid fixation of equipment on packing box and tray, and the stability of equipment in the container.

• The first layer: wrapped with foam film and stretch film for the special components for the sake of avoiding moisture.
• Second layer: adopting small square plywood block and strapping belt to fix the machine inside the plywood box
  
• Third layer: the machine itself has screw fixing holes, so it can be tightly fixed on the bottom of the plywood box through screw and nut.
• Fourth layer: inside the container, the gap between machine parts are filled with compact layout to avoid shaking. At the same time, reinforcing between the bottom of the container and plywood boxes once again, furthermore using hanging steel wire protection.
