What is necessary for motor encapsulation, IC encapsulation, and substrate encapsulation? 【Advantages of Transfer Molding Machines】 ■ Since the softened molding material is injected, damage to the insert is minimized! ■ By placing the molding material while the mold is closed, dimensional accuracy is improved! ■ Characterized by thin burrs, making finishing work easy! 【Yamashiro Seiki Seisakusho's TF Molding Machine: Three Concepts】 ■ Emphasis on low speed and low pressure! - To prevent damage to insert work and deterioration of product performance due to resin, control is focused on low speed and low pressure as much as possible. ■ Outstanding workability! - Capable of handling various shapes of insert work while also considering automation, adopting a lower mold slide table method. ■ Balancing control stability and energy saving! - An energy-efficient inverter pump is used for mold clamping control. - Electric control using a servo motor is adopted for TF control, achieving stable independent control and energy saving. *For more details, please refer to the PDF document or feel free to contact us.

Our company is engaged in the manufacturing and development of various molding machines and the production of molds. We have recently renovated our Yamaguchi office (Mine City, Yamaguchi Prefecture). Utilizing about half of the space, we have opened "TECH BASE MINE," which showcases prototypes of thermosetting resin transfer molding, as well as various molding machines and weighing devices. 【Equipment Overview】 <Prototype Room A> ◎ Hybrid transfer molding machine "VHS52-T6EV-WIDE" ◎ Preheating furnace, preheater device <Prototype Room B> ◎ Hybrid transfer molding machine "VHS52-T6EV" ◎ Preheating furnace, preheater device <Exhibition Hall> ◎ Small electric motor with slide table "VES5-S8EV" ◎ Small electric motor with rotary table "VER15-S15EV" ◎ Resin weighing device "TB3050" ◎ Dedicated molding machine for color plates "CP50-40" ★ If you wish to visit or prototype, please apply through "Contact Us." You can view details of some equipment via "PDF Download" or feel free to contact us.

Here is an introduction to the differences between vertical and horizontal injection molding machines. In vertical machines, the mold opens and closes in the vertical direction, and the installation footprint is often about half that of horizontal machines, resulting in approximately double the productivity per floor area. On the other hand, horizontal machines open and close the mold in the horizontal direction, making it easy to arrange multiple machines in parallel and collect molded products on a conveyor. **Features of Vertical Machines:** - Easier to perform insert molding - Advantageous for precision molding - Easier to accommodate complex and sophisticated automation - Easier to achieve uniformity in resin flow within the mold and temperature distribution of the mold - Capable of using "removable molds" that can be produced at a low cost due to their simple structure *For more details, please refer to the related link page or feel free to contact us.*
