山五化成工業 Company Overview

As a plastic solution partner, we will solve your resin-related problems!

Our company is engaged in injection molding, prototype and mass production of resin compounds, assembly of automotive parts, and extrusion molding as a plastic solution partner. (Transition certification for ISO 9001:2015 in May 2019) In the compound business, we use a small twin-screw prototype machine (manufactured by Japan Steel Works, TEX30α, with a discharge capacity of approximately 10-40 kg/h) for the development and prototyping of original compounds and masterbatches. We can also handle mass production using a twin-screw extruder compatible with the prototype machine (with a discharge capacity of approximately 100-200 kg/h). We can accommodate high-fill compounds using a side feeder, high-heat-resistant resin compounds (capable of withstanding temperatures up to around 350°C) using brass cast heaters, and reactive compounds that leverage high L/D ratios. In the injection molding business, we own seven injection molding machines ranging from 100t to 660t class, and we have a system in place to handle everything from mold design to the production and quality control of actual products for the nursing care, infrastructure, agricultural machinery, and automotive interior fields. Please feel free to contact us if you have any requests. TEL: 0827-85-0231, Development and Sales Department, Eda
