Cannot Be Done with 3D Printers!
Reasons for Our Commitment to Cutting Processing
While the world is advancing towards 3D, it is necessary to enhance the ability to interpret drawings, understand the design intent from dimensional tolerances and geometric tolerances, consider where the essence of the product lies and how it will be used, and select the optimal processing method and process settings for that product. Recently, the prototyping of resin products using 3D printers has been increasing, but we leverage the strengths of "cutting processing" to provide high-quality, high-precision prototype models.
- Reason 1:
- High Quality and High Precision
- Because cutting has superior dimensional accuracy compared to 3D printing.
- Because cutting can provide products with higher-precision surface roughness. *Capable of reproducing Rz3.2 or less
- Reason 2:
- Not Only Shape Reproduction but Also Added Functionality
- Because cutting can provide products made from materials closer to those used in molding compared to 3D printing.
- Because the materials used are closer to those used in molding, products with high mechanical properties such as strength and heat resistance can be provided.
- Because cut products have excellent airtightness and can be used for tests such as storing and flowing liquids.
- Reason 3:
- Flexible Response Tailored to Customer Requirements
- Because cutting has shorter processing times compared to 3D printing, it can handle higher volumes of work.
- Because cutting processing can be applied to existing products for additional processing or modifications.
Processing of Glass-Fiber Reinforced Resins
Glass-fiber reinforced resins, often used as mechanical components in the automotive industry (such as PBT-GF30%, PA66-GF30%, PPS-GF40%), are materials we research daily in our company for cutting. We have conducted extensive research especially on "warping," analyzing shapes and warp directions in advance to realize processing methods that minimize the impact of warping. In terms of quality assurance, we utilize 3D measuring machines and the latest hybrid shape and roughness measuring instruments to provide higher-precision parts.
Multi-Surface and Complex Shape Machining
By performing multi-surface machining with a 5-axis machining machine, we reduce dimensional errors that occur during process changes. We also achieve cost reductions by eliminating unnecessary jig costs and setup costs. For complex shape machining, we submit materials in advance, including explanations of any remaining R (radius) during processing and processing methods, confirming the shapes required in terms of specifications before proceeding with processing, thereby delivering products with a balanced QC.
Fields Where Umehara Model's "Prototypes"
Are Used
Amusement
In the domestic industry, the amusement field is a very large market. Our company has strong support capabilities in prototypes for this amusement industry as well. We believe that short delivery times are one of the major themes in this field. To reduce the burden of prototype ordering as much as possible for our customers, we provide total support including resin parts, secondary processing, sheet metal parts, metal pins, and spring processing. This not only reduces the effort required when ordering prototypes but also has the advantage of resolving issues such as data interference and product fitting, which may be discovered after delivery, in advance. In secondary processing, we can reproduce treatments similar to mass production, such as masking painting, figure painting, vacuum deposition plating, electrolytic plating, and laser peeling.
Automotive
We have been involved in prototyping at the development stage for many years for the automotive industry, which is the mainstay of Japanese manufacturing. We have extensive experience in handling prototypes of exteriors such as bumpers and doors, interiors such as steering wheels, from verification models to mechanical parts. We specialize particularly in processing glass-filled resins with dimensional accuracy of about 0.02 mm. We conduct meticulous meetings with our customers and propose process settings for cost reduction, considering the precision and quantity of the parts to be produced. Our VA/VE proposals have been very well received at in-house exhibitions of major automobile manufacturers and Tier 1 suppliers.
Home Appliances and OA Equipment
Our technical capabilities have been highly evaluated in the production of home appliance and OA equipment parts. Even without drawings, based on meetings, we guarantee the necessary dimensional accuracy such as hole diameters and mounting pitches. We always achieve high-precision dimensional accuracy. In our company, we can handle secondary processing such as painting and plating as design features. Leveraging our extensive experience in producing working models for products in other industries as well, we can create prototypes that combine design models and working models.
