The expansion of the factory building has been completed [Medical Plastic Parts - Fluororesin Yōwa].

Proven track record in components for artificial dialysis system piping and beverage piping!

The characteristics of fluoropolymer, such as "non-stickiness (difficulty for components and dirt to adhere)," "high heat resistance," and "resistance to strong acids and alkalis," combined with Yowa's processing technology, have achieved a reduction in cleaning time. - The cleaning time for piping components carrying high-viscosity liquids has been shortened. - In piping used for producing multiple beverages, there is no adhesion of components, resulting in reduced residual odors from previously flowing beverages and shortened cleaning time. - Cleaning with hot water is desired for sterilization. Sterilization is needed in high-temperature environments. - The cleaning solution is resistant to strong acids and alkalis, leading to a reduction in cleaning time.

Up to 70% smaller! Achieve downsizing of piping structures with weld-free piping that requires no assembly.

Through our unique PFA welding technology, we directly connect fittings to each other and join tubes to machined manifolds, forming a piping structure. - Fittings are directly connected, resulting in a more compact piping system. - Assembly is no longer required, reducing assembly labor. - There are no leaks due to the connection between fittings and tubes or the switch from welded piping. - By combining with machined products, multi-port manifolds can be achieved even in small diameters (Φ4 and above). - The number of parts has been reduced, leading to cost savings. - We can accommodate everything from small quantities to mass production by combining with machining and injection molding.

For medical applications such as dialysis tubing, catheters, and endoscopes. For your medical device concerns, leave it to Yowa, specializing in fluoropolymer processing.

PFA welding is a joining method that differs from welding techniques, as it integrates the objects by heating and melting the joining surfaces and applying pressure. The joint area achieves strength equivalent to that of the base material, similar to welding methods. 【Characteristics of Fluoropolymer: "C-F Bond"】 Fluoropolymers have a strong bond between carbon (C) and fluorine (F) atoms known as the "C-F bond," which results in high bond energy and a chemically inert and stable molecular structure. This "C-F bond" provides characteristics such as heat resistance, chemical resistance, and non-stick properties, demonstrating excellent properties for medical device applications! ■ Cleanliness ■ Chemical resistance ■ Heat resistance ■ Non-stick ■ Elasticity 【Solving These Concerns!】 ■ Concerned about impurities leaching from the welded area / contamination residue... → Solved with PFA welding technology that "joins" using only heat and pressure without adhesives or solvents! ■ Want to reduce costs... → Possible to reduce the number of parts and significantly decrease piping installation effort and cleaning time. ■ Want to improve liquid leakage... → Solved with "PFA welding" that smooths the welded area! *For more details, please refer to the PDF document or feel free to contact us.

Improved functionality with different material embedding and hollow structures! Expanding the possibilities of PTFE!

PTFE welding is a method of joining PTFE materials using heat and pressure. The bonded area has a strength equivalent to that of the base material. With PTFE welding, it is possible to create products with the following shapes by combining it with machining. 【Features of PTFE Welding】 ■ Embedding of Dissimilar Materials The characteristics of fluororesins and the dissimilar materials being embedded complement each other, enhancing functionality. ■ Formation of Flow Paths PTFE welding allows for the formation of flow paths within components. The flow path structure becomes compact, contributing to space-saving. ■ Clean Welding Method Since it joins using only heat and pressure, there are no impurities intervening, allowing fluororesins to exhibit their excellent characteristics in various environments.

PTFE bonding PTFE welding technology

This is a method used for joining fluororesin, which is our specialty. Due to the excellent "non-stick" properties of conventional fluororesin, achieving reliable bonding has been considered very difficult. However, we have developed a unique technology that not only allows for reliable bonding of fluororesin but also realizes beadless welding, taking into account the functionality of piping components. (Patent pending) (Customer Benefits) ● It becomes more compact compared to conventional piping, allowing for downsizing of equipment. ● The labor required for our own piping installation can be significantly reduced. By maximizing the use of welded piping, the number of joints can be reduced by up to 70%* (*according to our calculations). ● It is suitable for short delivery times. ● Replacement during maintenance is easy. ● It allows for designs that are not constrained by conventional wisdom. ● In collaboration with Flowell Co., Ltd., we provide innovative piping components using PFA joints and joint welding processing.

ISLFD is an international conference where researchers and engineers involved in freeze-drying and related technologies gather from around the world to exchange information and discuss research results and technological trends. Through our sponsorship at this conference, RheaVita will present the latest information on spin freeze-drying technology. At our booth, in addition to introducing the latest information about spin freeze-dryers, we will be open to consultations on a wide range of topics, including research and development, feasibility testing, scaling up, and comparisons with existing processes. We aim to create a valuable platform for information exchange for those asking questions such as "What is spin freeze-drying?", "What are the differences from conventional freeze-drying processes?", "What are the challenges of scaling up and reproducibility?", and "What new formulation and manufacturing approaches should be considered?". Additionally, individual meetings will be possible during the conference. If you contact us in advance, we will secure a meeting opportunity at a time that is convenient for you.
