Flexibly accommodating compression springs of all shapes. Designing specifications according to the usage environment and required load conditions. Please feel free to contact us if you have any design concerns.
Also known as compression springs, these are the most commonly used springs with a wide range of applications and various shapes. By changing the material diameter, coil diameter, and winding pitch, they can adapt to any usage environment. Our company can accommodate wire diameters from 0.015mm to 13.0mm through molding machines or manual processing, but please consult us for other sizes. A characteristic of our compression springs is that they are beautifully wound and stand straight. Of course, we can also provide polishing treatment for the ends of the springs and shot peening processing. - We offer compression springs of various shapes and characteristics with reliable technology. - Manufactured with materials and surface treatments tailored to your desired usage environment. - Prototypes can be made from just one piece. Small orders and short delivery times are also welcome. - We can also accommodate composite products that combine compression springs and wire processed products. - Shot peening processing can be handled in-house with our own machines.

basic information
◎ Our compression springs stand straight and beautifully. We refer to this "straightness" as "perpendicularity," and we can manufacture to JIS Grade 2 level, as well as JIS Grade 1 and higher levels, so please feel free to consult us. ◎ Komura Industries is also very skilled at manufacturing small compression springs! Please feel free to inquire! We accept orders for compression springs made from ultra-fine materials with a wire diameter of φ0.015 mm. We can flexibly accommodate materials such as piano wire, stainless steel wire, phosphor bronze wire, and plated wire. ◎ We also accommodate the manufacturing of large compression springs with a wire diameter of up to 13 mm. Of course, we can also handle grinding processes for both ends. We can accept orders starting from just one piece, so please feel free to contact us. We can flexibly accommodate materials such as SWPA, SWPB, SUS304WPB, SWC, and SWOSCB. ◎ We can also flexibly accommodate various shapes of compression springs. Barrel-shaped, tapered, uneven pitch, pig tail... please feel free to consult us.

We also accommodate the production of push springs with a cylindrical shape. We can also perform polishing on the coiled ends. These push springs have a variety of applications, such as in health equipment like massage chairs and mechanical parts. We also support polishing of the coiled sections! Please feel free to contact us regarding wire diameter, material, shape, size, and more.

It is also possible to manufacture pig tail end compression springs. We can also process compression springs with one end shaped like the character "no," known as pig tail ends. Additionally, as shown in the image, it is possible to perform polishing on both ends. The product in the image has been treated with trivalent chromate plating for surface treatment.
-
We also accommodate the manufacturing of conical springs (taper springs). We can manufacture compression springs known as conical springs or taper springs. Depending on the wire diameter and outer diameter, we can also perform polishing on the seated winding part, so please feel free to contact us.
-
The seat coil part is compatible with open-end compression springs. The finish of the seat coil part of the compression spring can be either a typical closed-end or an open-end like the one in the image. The spring in the image is a very rare type, with one side being an open end and the other side having a closed end with polishing. Additionally, there is a tapered processing visible on the body. Customers who are struggling with the treatment of the seat coil of compression springs are encouraged to contact us.
-
Manufacturing of compression springs with different outer diameters on one side of the seat coil. It is possible to change the diameter only on the seat coil parts at both ends of the compression spring. The spring in the image is made of stainless steel and is a version with a larger diameter on one side only. Our company turns your desires into reality! Please feel free to consult with us.
-
It is a special spring called a tapered spring or conical spring. As the load is gradually applied, the spring compresses close to the wire diameter, creating space at the installation location. Depending on the wire diameter, it is also possible to polish the seating coil (on both ends or one side), so please feel free to consult us.
-
We can also manufacture compression springs (push springs) using beryllium copper wire for springs. We are capable of producing push springs using beryllium copper wire materials such as C51900W-H and PBW. We can also accommodate polishing at both ends of the coil. In addition to push springs, we can handle various shapes of wire processing as well. Please feel free to consult with us.
-
A composite type of conical spring (taper spring) and a regular compression spring. It can respond to two different loads, making it effective for space-saving. Upon request, we can also accommodate both ends of the seat coil being polished or polishing on one side only.

Company information
◎ Difficult processing that cannot be done by machines will be handled by our skilled staff while listening to your requests. Please consult us even for springs that could not be manufactured by other companies. ◎ During manufacturing, we confirm quality with a "Manufacturing Check Sheet," and after production, we conduct load tests and projection inspections using our in-house spring testing machine, issuing an "Inspection Report" based on the results. We deliver high-quality products consistently. We have obtained ISO 9001:2015 certification. ◎ We will definitely make it cheaper than anywhere else! ... Although we cannot say that, we are committed to delivering at your desired price as much as possible. By having strong connections with material wholesalers and in-house production of jigs and molds, we strive to provide low-cost solutions not only for mass production but also for small orders that tend to incur higher costs.
