JB04 Series Table Small Press Machine
The JB04 series are motorised bench presses from 1 ton to 5 tons, sized for the production work that a hand press cannot keep up with. Four models cover 10 kN 20 kN 30 kN and 50 kN nominal pressure with motors of 0.37 kW 0.55 kW and 0.75 kW. Stroke rate is what separates these from a manual press: 245 to 257 strokes pe...
What This Machine Does
The JB04 series are motorised bench presses from 1 ton to 5 tons, sized for the production work that a hand press cannot keep up with. Four models cover 10 kN 20 kN 30 kN and 50 kN nominal pressure with motors of 0.37 kW 0.55 kW and 0.75 kW. Stroke rate is what separates these from a manual press: 245 to 257 strokes per minute means a bench operator working with a foot pedal can hold a steady production rhythm instead of pumping a lever. Slide stroke is 40 mm on JB04-1 and JB04-2 and 48 mm on JB04-3 and JB04-5, with maximum shut heights from 160 mm to 230 mm and stem hole diameters from 20 mm to 30 mm. Bed sizes run 270 x 270 mm up to 380 x 380 mm and weights from 89 kg to 238 kg, so the smaller models sit on a strong bench while the larger pair need their own stand. Control is by foot pedal or by hand. Packing is in a plywood case.
Why Buyers Choose This Machine
- 1 to 5 tons of force from a bench sized machine so light production does not need a floor press
- 245 to 257 strokes per minute supports a steady production rate on repeat parts
- Foot pedal control leaves both hands free for feeding and removing parts
- Four capacities from 10 kN to 50 kN so the press matches the operation rather than oversizing it
- Shut heights from 160 mm to 230 mm accept a range of die heights
- Bed up to 380 x 380 mm supports larger dies and strip feeding
- Low motor power of 0.37 to 0.75 kW keeps the electrical installation simple
Where JB04 Series Table Small Press Machine Earns Its Place
Problems It Solves
- A manual press cannot hold a production rate across a shift
- A full sized floor press is oversized and expensive for small parts
- Hand operation ties up one hand that should be feeding the part
- A short shut height limits the dies the press can accept
- A small bed will not support a progressive die or a strip feed
Who It Is For
- Sheet metal and stamping workshops running small parts
- Electrical and electronic component manufacturers
- Hardware and fastener producers
- Assembly operations doing riveting and insertion work
- Distributors supplying bench press machines
Application Scenarios
- Blanking and piercing small sheet metal parts in production
- Riveting and staking assemblies on a bench line
- Pressing bushes and inserts into components
- Forming small brackets clips and terminals from strip
- Embossing and marking operations on small parts
- Short run production and sampling ahead of a larger press

How It Is Built and What Can Be Changed
Operations Performed
- Punching
- Blanking
- Piercing
- Riveting
- Pressing
- Embossing
Quality Control
- Slide stroke verified at 40 mm or 48 mm against the model specification
- Stroke rate measured under power against the listed strokes per minute
- Shut height adjustment checked through its range
- Ram to bed alignment checked before the press is released
- Foot pedal and guarding function tested and motor current checked
- Packing checked against the plywood case size and gross weight
Customisation Options
- Model selected by the force required from 10 kN to 50 kN

- Foot pedal or hand control specified with the machine
- Supply voltage frequency and phase built for your market
- Dies and tooling quoted against your part drawings
How It Compares With the Alternatives
| J01 series manual mini press | The J01 presses are hand or foot operated at 0.5 to 6 kN for light bench work; the JB04 machines are motor driven at 10 to 50 kN and run at around 250 strokes per minute |
|---|---|
| Full size floor mounted power press | A floor press gives far more force and die space but needs its own footprint and installation; the JB04 sits on a bench or stand at 89 to 238 kg |
| Hand riveting and hand punching | Hand work cannot hold the rate or the consistency of a powered press with a set stroke and shut height |
Running the Machine
Step 1
Mount the press on a bench or stand rated for the machine weight from 89 kg to 238 kg
Step 2
Fit the die in the stem hole sized for your model from 20 mm to 30 mm
Step 3
Set the shut height so the die closes correctly within the model maximum
Step 4
Connect the supply to the 0.37 to 0.75 kW motor and check the direction of rotation
Step 5
Try the setting on scrap material before starting the production run
Step 6
Use the foot pedal so both hands feed and remove the part
Step 7
Check the die and the shut height setting at the start of each batch
