Product category: Molding
Sharp Points Medical Device Part
Material & Thickness
Stainless Steel 0.15mm

Past and Current Technology
This product used to be made by grinding one-by-one. So the product can be supplied at extremely expensive price. It is possible to lower the cost if it is made by lathe. But it could only make coincidently few pieces out of a thousand pieces.

JKB’s New Technology
JKB has developed truly groundbreaking technology of making this product by stamping and we achieved making a sharp edge of 6μm in all directions. Therefore we are able to supply this product within 1/1000 of the past price.
We contribute a lot to the medical field to enrich peopleʼs health care through supplying our new product.

Product category: Molding
Filter
Material & Thickness
Stainless Steel 0.15mm

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.

JKB’s New Technology
We are successful in stamping more than 120 small holes within the area of 1/6th of a 10-cent 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.

Product category: Molding
Micro Clip
Material & Thickness
Beryllium Copper Alloy 0.06mm

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.

JKB’s New Technology
We successfully make this form at an accuracy of ±10μm using a progressive die. This process is exceptional taking into consideration the extreme thinness of the material being manipulated.

Product category: Molding
Offset Strip Fin ( Stainless Steel )
Material & Thickness
Stainless Steel 0.3mm

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.

JKB’s 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.

Product category: Molding
Banana Plug
Material & Thickness
Stainless Steel 0.2mm

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.

JKB’s 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.

Product category: Molding
Spherical Body
Material & Thickness
Brass 0.2mm

Past and Current Technology
It was impossible to make a spherical object from a plate without having an opening area on the shape.

JKB’s New Technology
We are successful in stamping completely sealed spherical body from a flat plate.

Product category: Molding
“Cylinder”+”V Shape Wing”
Material & Thickness
Nickel

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 Vshaped wing.

Feature of Part
We are successful in making the entire shape in one strike using a progressive die. We also achieve a circularity of 20μm for the circular part of this product that includes a V-shaped wing.
