PFA fusion welding is a joining method that integrates objects by heating and melting the joining surfaces and applying pressure, unlike welding techniques. The joint area achieves strength equivalent to that of the base material, similar to welding methods. **Features of PFA Beadless Welding** ◆ No concern for impurity leaching Since it joins without using adhesives or solvents, but rather through heat and pressure, there is no worry about impurities leaching from the welded area. ◆ Increased reliability of the joint The welded area is completely integrated, eliminating concerns about liquid leakage. ◆ Suppression of biofilm formation The non-stick property of fluororesin and the internal smoothing achieved through beadless welding prevent stagnation at the joint. Additionally, our company conducts the entire manufacturing process of fluororesin in-house, from mold forming of processing materials to product processing using cutting and welding techniques, and injection molding suitable for mass production. This allows us to provide a one-stop solution for product creation from prototyping to mass production. Furthermore, we respond to customer trust through a thorough inspection system and management of manufacturing history. Customers considering the launch of new products or parts can confidently entrust their needs to us.

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.

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.
