Yasojima offers high-precision resin machining technologies that have been refined for over 80 years. We select the most appropriate machining processes based on the mechanical and physical properties of the material used and the shape of the product as well as manufacture resin-based products to suit your end-use goal.
Machining accuracy and variation reduction, the accuracy of free-form shapes, microfabrication, thin wall machining, complex welding processing, improvement of surface roughness, and burr-free machining are all features 3D printing and machining with Yasojima can bring to your project.
We can help you identify the critical-to-quality features of your project, define what mechanical and physical properties are key, select the most suitable machining and 3D printing materials, and present manufacturing options to suit your timeline and end-use goal.
Achieve extremely fine grooving with no variation in dimensional accuracy.

Intricate R-curved surfaces machined under conditions that eliminate the occurrence of damage, cracks, and deformation during the machining process.
Micro-level flatness, polished mirror finishes, and burr-free machining are all features 3D printing and machining with Yasojima can bring to your project. By selecting the most suitable material and finishing process, it is possible to achieve the required finish at a micro level.

There are many ways to control surface roughness depending on the material used and design of the product. Flawless mirror finishes can be achieved if the machining process is carefully controlled. Surface roughness can be reduced by controlling vibration, choosing the ideal machining technology and cutting tools, and working with the most appropriate material.
Any inconsistencies or contaminants present during precision machining parts will affect the quality of the finish and efficiency of production. Even precision machined parts need finishing after rough machining to achieve the desired results.
Yasojima has developed a unique system to control the surface roughness of free-form parts and can achieve a surface roughness of Ra0.09μm. Our manufacturing facilities are temperature and humidity controlled and feature vibration-proof equipment and flooring.

PEEK plastic welding can produce a variety of shapes that cannot be achieved by machining alone. PEEK, which is highly resistant to heat, can be extremely difficult to weld; however, Yasojima has invented PEEK welding techniques that eliminate the possibility of defects such as voids and thermal deformation during manufacturing. Our exclusive welding processes ensure that part strength is uncompromised.

In addition to machining, Yasojima can also assemble manufactured parts regardless of material.
Yasojima provides innovative 3D printing and machining solutions that give you freedom of design and a seamless transition from prototyping, manufacturing, and assembly of your custom end-use parts.
