Samples

Sample No.1

Sample No.1

 
Past and Current Technology
To stamp this product using the current technology on the market is impossible without the separation of the metal into small pieces. Therefore, the processing conditions required are extremely complicated and highly complex.
 
New Technology
JKB has been able to develop truly groundbreaking technology, utilizing a combination of lancing and drawing of stainless steel. We are successful in making this form using one progressive die. We are the first company in Japan to achieve this solution.
 
 
Sample No.2

Sample No.2

 
Past and Current Technology
This product was previously made using photo etching which required an ultra microscopic process. As a result , production costs were high.
 
New Technology
We are successful in stamping more than 120 small holes within the area of 1/6th of a small coin. The tolerance of the hole pitch is less than 3μm. The price of this product is greatly reduced to 10% of the current market price.
 
 
Sample No.3

Sample No.3

 
Past and Current Technology
In the past, this product was extremely difficult to make since the stamping required a very high level of precision, as the material is only 0.06mm in thickness.
 
New Technology
We successfully make this form at an accuracy of ±10〜50μm using a progressive die. This process is exceptional taking into consideration the extreme thinness of the material being manipulated.
 
 
 
Sample No.4

Sample No.4

 
Past and Current Technology
This product was previously difficult to make because the form has a V-shaped wing inside a circular shape which required a precise circularity. This product was made by combining two separate parts , one being circular in shape , the other having a V-shaped wing.
 
New Technology
We are successful in making the entire shape in one strike using a progressive die. We also achieve a circularity of 15μm for the circular part of this product that includes a V-shaped wing.
 
 
Sample No.5

Sample No.5

 
Past and Current Technology
It was difficult to make this product by
a progressive die because it was hard to design a carrying web (a connecting part required in the shape for feeding the raw material ). The processing of this form required several steps using a combination of different dies. As a result, this product was supplied in small quantities and
at a high price.
 
New Technology
We are successful in stamping this product using one progressive die.
This form is made by stamping out, bending and squeezing with one strike of the die. Therefore, we are able to supply this product in large quantities and
at a significantly lower price.
 
   
 
 
 
 

Progressive Stamping : Progressive stamping is a metalworking method that encompasses plural processes such as blanking, bending and drawing combined with a sheet metal feeding system in one die.
