～A Must-See for Those Struggling with Off-the-Shelf Products～ - Recently, space-saving designs have progressed, and off-the-shelf products no longer fit, so custom-made items that match the space are necessary. We would like you to accommodate not only size but also lightweight and compact designs. - There are no off-the-shelf products in the desired size. We want to create something that fits our company's specifications. - We are concerned about the strength of off-the-shelf products. We would like you to process them to enhance their strength. - We want to create products using high-strength materials that ensure safety. - Using metal as a material increases costs. Is it possible to use synthetic resin instead? - There are no off-the-shelf products that match the chemical agents we use! We want to create something with a different material. - Considering eco-friendliness, we would like products made from recyclable materials. - We are not very familiar with chemical resistance, so we would like you to provide information on that. ● Please download our catalog for more details about our company.
