Machining, resin prototyping, plastic prototyping

Machining, resin prototyping, plastic prototyping

There is a reason for carving it out.

Until now, prototype plastic parts were generally made using "machining," but with the increasing use of "3D printing" for prototypes, they are often compared. Each method has its own characteristics, and it is necessary to choose the appropriate one depending on the object and purpose. For prototypes that require functional evaluation such as precision, strength, heat resistance, and water resistance, "machining" is the most suitable. Due to its ability to achieve very high precision, it can also be used as parts for final products. Please consult us first for high-quality, high-precision prototype models that leverage the strengths of "machining."

[Video Now Available] Prototype Using ADC12

[Video Now Available] Prototype Using ADC12

Are you struggling with prototypes of die-cast products? Do you think ADC12 can only be used for die casting?

ADC12 is an aluminum alloy that excels in wear resistance, machinability, and castability. It is widely used in automotive parts and is one of the most commonly used alloys in aluminum die casting. As another option for prototyping, why not conduct a machined prototype using the same "ADC12" as the mass-produced products? *For more details, please watch the introduction video below!
