[Application Recruitment] Why not properly create a prototype even for "soft products"?

Various problems that arise during the processing stages, depending on the products and materials used when creating trial parts, can be solved using the "vacuum casting method." *Free sample production available.

The "Vacuum Injection Molding Method" involves creating a master model from easily machinable hard materials, such as those made with a 3D printer, then reversing it into silicone, pouring in urethane rubber, and molding it. This allows for the creation of complex master models without directly machining the rubber, so all that remains is to replicate it with a soft material. ★ We are currently accepting customer inquiries for "Can we do this?" We will solve it with our processing technology! ★ ▶ Please apply through the online application at the URL below, or download the PDF materials, fill in the necessary information, and return it via fax or email. 【Features of the Vacuum Injection Molding Method】 ■ Supports small lot sizes and short delivery times ■ Capable of reproducing complex shapes ■ Hardness can be selected from 20 to 90 degrees ■ Offers a wide variety of color options * For more details, please download the materials or contact us.

Vacuum casting allows for detailed expression! It accommodates coloring and various hardness levels.

Various issues that arise during the processing stages, depending on the products and materials used when creating trial parts, can be resolved using the "vacuum casting method." *Free sample production available.

The "Vacuum Casting Method" by Sansei Workshop can faithfully produce replicas of industrial parts, functional components, and medical parts, including those made from soft rubber materials like polyurethane rubber (transparent resin), as well as industrial robots. Even if the old machine parts are no longer manufactured, we can create the same items if we have a master product. Additionally, by producing in a vacuum, we can avoid air bubbles and reproduce fine details. 【Do you have any of these concerns?】 - You have ideas you want to create but haven't been able to execute them. - You don't know any manufacturers that can produce even one piece. - You're worried about the cost. - You want to meet the delivery deadline for the prototype parts you've ordered. If you have such concerns, this campaign might be able to solve them! Please take this opportunity to apply! *If you would like to request sample production, please apply online at the URL below, or download the PDF materials, fill in the necessary information, and return it by fax.

Free gift of urethane rubber cast hardness samples! 【Vacuum casting method】

Even for soft products, why not create proper prototypes? With the 'vacuum casting method,' we can manufacture prototypes from just one piece using urethane rubber casting!

When attempting to mass-produce "soft products" like rubber and elastomer products, there is always a sense of unease because one has no choice but to create the final mold immediately, even for complex shapes. With our "vacuum casting method," urethane rubber casting is possible. There are a wide range of hardness options from 20 to 90 degrees, and coloring of the material is also flexible. By accommodating prototype rubber products, we can mitigate risks during mass production! ★ Urethane casting using the vacuum casting method can handle complex shapes at low cost and with short lead times, even for just one piece. 【Features of Vacuum Casting】 - Supports small lots and achieves short lead times - Capable of reproducing complex shapes - Abundant options for hardness and color selection We are currently offering hardness samples to the first five companies that apply! Please take the opportunity to try out our sample products made using the vacuum casting method! *If you would like a sample, please feel free to contact us using the information below.

Low hardness rubber is also available for prototype and development! *Technical materials provided!

Prototyping and development are possible for soft materials like rubber that cannot be machined, or items that are too few in number to create molds! *Technical materials are available for free!

Even with soft polyurethane rubber material, it is possible to create prototype parts using "vacuum casting." Since functional parts, industrial parts, and medical parts are also produced in a vacuum state, it has become possible to faithfully reproduce them. 【Partial content of technical documentation】 ■ What is vacuum casting ■ Types and properties of casting materials ■ Functions of vacuum casting ■ Comparison of working time ■ Examples of processed sample parts (with photos) etc. *For more details, please download the documentation or contact us directly.

A must-see for those involved in manufacturing development! Do you have any issues with prototype parts?

Technical documentation: A thorough explanation of the process of "vacuum casting," which can faithfully reproduce master models, including casting materials, advantages, and disadvantages!

Even with polyurethane rubber, which is one of the soft rubber materials, it is possible to faithfully produce replicas of industrial parts, functional components, and medical parts, including industrial robots. We will publicly disclose the technical fees for such prototype parts all at once, along with analysis data, photos, diagrams, comparison tables, and more! 【Contents】 ■ What is vacuum casting?   ■ Master model ■ Casting materials     ■ Working time for casting methods ■ Advantages and disadvantages of casting methods ■ Introduction to sample processing… and more *If you would like technical materials, please download them or contact us directly.

What is vacuum injection molding? ~ Vacuum vs. Atmosphere ~ *Technical materials available!

We are offering a technical document featuring vacuum casting techniques made from rubber materials!

"Vacuum casting" is a method that uses silicone molds instead of metal molds to produce replicas that faithfully reproduce the master model. The work is conducted in a vacuum state to ensure that the injected resin reaches every corner without bubbles. This document includes the work procedures for "vacuum casting" and experiments/results comparing "vacuum casting" and "atmospheric casting." [Contents] ■ What is vacuum casting ■ Why work in a vacuum ■ Experiment: Vacuum vs. Atmospheric ■ Results *For more details, please refer to the PDF document or feel free to contact us.

Prototype of polyurethane rubber using silicone molding *Technical materials available!

Proposal for rubber prototype manufacturing methods

I believe that cutting processes will not yield accurate dimensions and shapes for items made of soft materials like rubber that have somewhat complex shapes. We must create the molding die while harboring these concerns. The "vacuum casting method" involves creating a master model from hard materials that are easy to machine, such as those made with a 3D printer, then inverting it in silicone, pouring in urethane rubber, and forming it. This allows for the creation of complex master models without directly machining the rubber, so all that remains is to replicate it with a soft material.
