To produce screw, two machines are necessary--Cold-heading Machine and Thread Rolling Machine:
1. Cold-heading Machine
To cut raw material wire according to length of finished screw and form screw head.
Main Technical Parameter:
Model No | Dia. of Screw (mm) | Length of Screw (mm) |
CDH4-40 | 2-4 | <=40 |
| CDH5-60 | <=5 | <=60 |
| CDH6-50 | <=6 | <=50 |
| CDH6-80 | <=6 | <=80 |
| CDH7-120 | <=7 | <=120 |
| CDH10-130 | <=10 | <=130 |
2. Thread Rolling Machine
To roll thread on blank shank of screw after being cold-headed.
Main Technical Parameter:
Model | Dia. of Threading (mm) | Length of Threading (mm) |
CDR4-40 | 2-4 | 4-40 |
CDR5-60 | 2-5 | 5-60 |
CDR6-80 | 3-6 | 5-80 |
CDR8-120 | 4-8 | 8-120 |
| CDR12-150 | 6-12 | 6-150 |
Besides the above two machines, another machine is optional---Self-drilling Machine
3. Self-drilling Machine
To make the self-drilling screw tip.
Main Technical Parameter:
| Model | Dia. of Screw (mm) | Length of Screw (mm) |
| CDD6-130 | 2.8-6.3 | 9.5-130 |
| CDD6-200 | 2.8-6.3 | 9.5-200 |
4. Washer Assembling Machine
To assemble the screw and washer automatically.
Main Technical Parameter:
| Model | Dia. of Screw (mm) | Length of Screw (mm) |
| CDA20-75 | 4.8-6.3 | 20-75 |
| CDA70-200 | 5.0-6.3 | 70-200 |
Q: What is the raw material for screw?
A: Low carbon iron wire, commonly from 1008 to 1022, different type of screw, different carbon content.
Q: Can you provide specification of raw material?
A: We will provide you size of raw material after we get diameter of shank of all screws.
Q: What is electrical supply of machine?
A: Our machine normally is 380V, 3P, 50Hz, but it could be as your requirement.
Q: Could one set of machine make all sizes of screw?
A: No, our machine has its production range, one machine could make screw with some production range.
Q: What is screw making machine woking progress?
A: The progress as blow: Raw material >> Cold heading >> Thread rolling >>Screw
Q: What is the power of screw making machine?
A: Our screw nail making machine is with different power ccording different reuipment for screw nail machine detailed ,please refer to our quotation.
