5-1/2 in. Reversible Bench Vise

 Company Introduction     

      Our company was established in 2006 and is a professional company specializing in the design, development, manufacturing, and sales of various molds, fixtures, gauges, automation, and precision components, gradually forming an integrated high-end green manufacturing.

The company has a professional design team and over 60 manufacturing personnel, as well as more than 50 precision machining equipment and high-end testing equipment; The company has passed the ISO9001:2008 quality management system certification.

The company started developing precision flat mouth pliers in 2019, and after three years of research and experimentation, finally successfully developed and put them into small-scale production; Simultaneously applying for 7 patents: 2 invention patents, 1 design patent, and 4 utility patents.

Our company is located in the beautiful coastal city of Yantai, at No. 17 Beijing South Road, HuangBohai New Area, Y

antai Pilot Free Trade Zone, with convenient transportation and beautiful environment; Welcome friends from all walks of life to visit and guide us, and call us for negotiation.

Working Principle 

vise combine the principle of lever and teeth,

Realize rapid adjustment of opening width, thereby achieving fast

Convenient; By utilizing the working principles of both screws and nuts,

The rotation of the screw will drive the nut to move along the axis of the screw,

Thus achieving the clamping and releasing of vise

Product Features

1. Convenience:

Within the clamping range, rapid pulling can be achieved to achieve quick clamping.

2. Clamping force energy storage:

Due to the special structure of flat pliers, thin workpieces only need to be gently clamped. The workpiece will not deform and will not loosen during processing. It is not easy to deform when clamping thinner workpieces.

3. Not upturned:

The positioning pin hooks onto the positioning groove, providing downward pressure to the movable jaw, effectively solving the problem of workpiece lifting during clamping.

4. High precision:

The entire clamp body has undergone high-temperature tempering, half a year natural aging treatment, and high-frequency quenching of the sliding surface. The machining accuracy is controlled within 0.015mm.

Multiple units are used simultaneously, with an error of 0.01mm, and both parallelism and perpendicularity are maintained within 0.01mm.

5. Long lifespan:

The average lifespan of the improved flat pliers is 15 years, and currently the material used is ductile iron 450, making the pliers body more sturdy. The clamping mechanism is fully enclosed and there will be no iron pins entering.

6. High cost-effectiveness:

Due to the use of film coated sand casting technology for all clamp bodies, the manufacturing cost has been greatly reduced. The price of precision flat mouth pliers with such many performances is much lower than that of products in the same class.
