Products

Sakamura Hot Art designs and manufactures five different product series.
We can also propose machines that meet your requirements.

HF Series
Hot Former
This series makes higher precision forming possible to meet customer needs for diversified, thinner products including bearing parts. Single ram structure #1 process: Closed die forming
Positioning accuracy of blank is improved during #1 process in the #0 setup process after cutting the material

● HF2100E
(21,000kN)

● SHF1300-3
(13,000kN)
(Hot former with billet supply system)

● HF1000E
(10,000kN)

● HF800-4
(8,000kN)

● HF600-3.5
(6,000kN)

● HF500-3
(5,000kN)

● HF250-3
(2,500kN)

HFW Series
Hot Former Wram
HF Series with a twin ram structure
Unlike conventional twin ram types (HNP, HBP, HPF), the 10 degree shift from the front dead center of the ram allows for load allocation and control of load fluctuation during bar end treatment.

● HFW1800E
(18,000kN)

● HFW1000-4
(10,000kN)

● HFW800-4
(8,000kN)

● HFW600-5
(6,000kN)

● HFW500-4
(5,000kN)

● HFW380-4
(3,800kN)

● HFW250-4
(2,500kN)

HPF Series
Hot Parts Former
Based on the HBP Series and suitable for various parts including bearing parts.

● HPF1300
(13,000kN)

● HPF160
(8,000kN)

● HPF600
(6,000kN)

● HPF120
(3,800kN)

● HPF100
(2,800-3,500kN)

● HPF80

HBP Series
Hot Bearing Press
This series was developed for forming bearing rings.
The twin ram structure and #1 process are separated. After cutting the material, the upset is conveyed to the #2 process using a thrust up pusher, allowing for simultaneous production of inner and outer bearings.
Furthermore, its DRT structure allows for the simultaneous production of inner, outer, and middle rings.

● HBP160
(8,000kN)

● HBP120
(3,800kN)

● HBP100
(2,800-3,300kN)

● HBP80
(2,000kN)

HNP Series
Hot Nut Press
First series developed by Sakamura, mainly for nut forming.
Features a twin ram structure with separate #1 process.
After cutting the material in the #1 process, the upset is conveyed to the #2 process using a thrust up pusher.

● HNP700
(7,000kN)

● HNP140
(4,800kN)

● HNP120
(3,500kN)

● HNP100
(2,300kN)

● HNP80
(1,600-2,000kN)

● HNP40

Close

We design everything about hot formers, from the actual machine to the forging tools.
We achieve highly reliable designs through 3D strength analysis of frames, crankshafts and other main parts.
In addition, we work hard to create new products and methods through die design based on forging simulation results.
Machining
Read description

Close

High precision part machining mainly through milling, lathing, and boring.
We produce die blocks and overhaul large-size parts using our large boring machine.
Production

Close

Technical prowess developed over long years of experience helps us achieve high precision equipment assembly.
In addition, we continually achieve better machine assembly through close coordination with the design department and from suggestions for improvement at the assembly stage.
Equipment
