![Case study: Piston [Phosphor Bronze]](https://image.mono.ipros.com/public/product/image/c73/2000701849/IPROS06705965608686763146.png?w=280&h=280)
Unique know-how! We can accommodate a wide range from prototypes to small lots and mass production.
Here is an example of the production of a "piston" made using phosphor bronze as the material. 【Production Example】 ■PDC2 Piston ■Outer Diameter: φ262 ■Inner Diameter: φ58 ■Height: 139 *For more details, please refer to the PDF document or feel free to contact us.
We can manufacture pistons in various sizes from Φ40 to Φ132.
IKY Piston Co., Ltd. has been a specialized manufacturer of pistons for 60 years, conducting consistent production and sales from casting to processing in Hamamatsu City. We possess over 300 types of molds and respond to all customer requests, from the production of special engine pistons to pistons for automobiles, motorcycles, and general-purpose engines. If you have any inquiries regarding pistons, please feel free to contact us. We can manufacture pistons in various sizes, from Φ40 to Φ132. We also produce forged pistons. 【Business Activities】 - Sales of pistons for automobiles, motorcycles, and general-purpose engines - Manufacturing and sales of Mastercam For more details, please contact us or download the catalog.
We will perform cutting of aluminum DC, and then assemble components such as shafts, springs, and washers.
We would like to introduce the "AT Piston" handled by Nisshin Seiki Co., Ltd. The component parts can be procured from partner factories. Aluminum DC is machined, followed by the assembly of shafts, springs, washers, etc. 【Specifications】 ■ Material: ADC12, Iron ■ Processing: Turning, Assembly *For more details, please refer to the PDF document or feel free to contact us.
The material is chromium-molybdenum steel SCM415! It has undergone carburizing and quenching, achieving a hardness of over HRC60!
The process of performing grinding-level machining through turning is called "hard turning." Pistons used in hydraulic systems for construction machinery require extremely high precision, with outer and inner diameter tolerances of ±2 microns, surface roughness of Ra0.4 microns, coaxiality of inner and outer diameters of 3 microns, and perpendicularity between the end face and outer diameter of 3 microns as the required specifications. At our company, after heat treatment, we simultaneously machine the outer diameter, inner diameter, and both end faces using NC lathes, achieving machining equivalent to grinding through turning. By consolidating four processes into one, we enable process shortening and cost reduction. Additionally, simultaneous machining allows us to guarantee the coaxiality of the outer and inner diameters and the perpendicularity to the end face. We have a shipping record of 10,000 units per month and can accommodate orders of up to 100,000 units. *For more details, please refer to the PDF document or feel free to contact us.
It has been processed using integrated molding and the increase-decrease meat method! This is a display item made with SAPH440.
We would like to introduce the exhibition item of "rotational molding" that we conducted. The thickness is t = 4.5, and the material used is SAPH440. It is processed into a "piston" through integral molding and variable thickness. Additionally, we can consider difficult-to-process materials, so please feel free to contact us when you have inquiries. 【Exhibition Item Overview】 ■ Material: SAPH440 ■ Thickness: t = 4.5 ■ Processing Details: Integral molding and variable thickness *For more details, please refer to the PDF document or feel free to contact us.
A steel piston with a one-piece structure that does not require welding!
We offer the 'MONOTHERM(R) piston,' designed as a one-piece structure for diesel engines, aimed at achieving lightweight and low-cost solutions for improved fuel efficiency. Depending on the application, you can choose between open and closed skirt structures. Please feel free to contact us if you have any requests. 【Benefits】 - Contributes to reduced friction at high temperatures due to a lower thermal expansion rate compared to aluminum pistons. - Potential for reduced cooling losses due to a lower thermal conductivity. - Reduced fluid friction due to a shorter skirt. - Lighter and more cost-effective than welded steel pistons. *For more details, please download the PDF or contact us.

The global market size for automotive pistons was valued at 11.38 billion USD in 2022, and it is projected to grow from 11.99 billion USD in 2023 to 18.27 billion USD by 2031, with a CAGR of 5.4% during the forecast period (2024-2031). Automotive pistons, which are cylindrical engine components, slide back and forth within the cylinder due to the force generated by the expansion of gases during combustion. The piston, piston rings, and piston pin make up the piston system. Through the connecting rod, this mechanism transmits the generated force to the crankshaft. The wheels of the vehicle are driven by the motion of the crankshaft, propelled by the mechanical energy produced by the engine. Diesel engines have a higher compression ratio than gasoline engines, so gasoline engine pistons generally have fewer piston rings. To withstand high temperatures, most pistons are made of steel and aluminum alloys.
