Cold extrusion press system is a kind of flexible connection designed according to construction site. It is an easy operated method to connect rebar, no need to precast rebar in factory.
The cold extrusion press coupler is extruded on rebar ends with the pressure of high pressure device. The test result of this kind of connection can guarantee the tensile strength of connection specimen is no less than 125% of the normal yield strength of rebar.
Cold extrusion press system is butt-to-butt connection which is suitable for applications that have both tension and compression requirements.
1. Suitable for repair or reform projects
2. Suitable for any rebar ends which are cold cut
3. No reducing the cross section area of rebar
4. All couplers have individual marks and batch numbers, so it is easy to trace raw materials. Totally produced in accordance with ISO 9001 standard.
1. Site preparation work: clean and straighten rebar.
2. Mark on rebar half length of the coupler.
3. Put the coupler in the gauge length to limit the extrusion area, and then mark on both ends of cold extrusion press coupler.
4. We can't extrude coupler outside the marking area after marking. We should extrude the coupler from middle to both sides.
5. Prepare hydraulic tools and install the corresponding pressure moulds. Prepare pump to connect power. If the motor is 380V or 440V, please rotate the switch to correct motor first.
6. Insert half length of the coupler onto rebar, connect according to indicating mark.
7. Extrude coupler with required pressure.
8. Stop extruding when it reaches the pressure value of specified size.
9. The process above is repeated many times according to each size requirements.
10. Prepare as many rebar end as need to connect.
11. Insert the rebar need to connect into the coupler extruded on the first rebar.
12. Repeat the extrusion process on the connecting rebar.The strength of cold extrusion press connection is no less than rebar normal strength in tensile tests. It can also do the ultimate mechanical tests which can break on bar outside the connection according to client's requests.
The parameter for standard rebar coupler
The Parameter for Standard Coupler (MM)
|Steel bar Diameter(MM)||Out Dia.of Coupler(MM)||Length of Coupler(MM)|
This coupler is widely used in bridge projects.
|Description||1.This type of rebar coupler match wuth rebar processed by cold extrusion press machine.|
2. Reliable quality, the raw material origin and production batch can be traced.
3. Full implemention according to ISO9001:2000 quality management system.
4. Can link rebar of diameter from 16 mm to 40mm.
5. The tensile strength of splicing is equal to the rebar.
|Advantages||1. The tensile strength of rebar splicing is very strong. It can meet standards at home and abroad such as: Chinese standard(JGJ107), American standard(UBC1997), British standard(BSB110), French standard(NF25-20-1), German standard(DIN1045) and ISO/WD15835(draft);|
2. Handy operation, no skilled operator needed;
3. Small need of impetus, not affected by the electric power supply in the site;
4. Environmental protection, no need to operate with open flames, not affected by weather

1. Are you a trading company or a factory? Do you have property ownership certificate of your company?
We are a factory that professionally manufacturing rebar connection machines and rebar couplers for 29 years. We have property ownership certificate of our factory.
2. Where is your factory? Is it free to visit?
Our factory is in Hengshanqiao Town, Wujin District, Changzhou City, Jiangsu Province, China. It's our pleasure to invite you to our factory. You can come anytime when we are at work.
3. What is the tensile strength and yield point of your couplers?
The tensile strength and yield point of couplers are different, according to their different raw materials, connection ways, thickness, length and other factors. Take our standard upset forging parallel thread coupler as example, the tensile strength can be 620~680MPa and the yield point can be 420~450MPa.
