The "MK700H" is a dedicated low-pressure molding machine for hot melt, with the maximum mold dimensions expanded to 300×200×150 (mm) and an enhanced clamping force of 75kN. This allows for the molding of larger insert works and molds with a high number of cavities, which were difficult to mold with the "MK600" and "MK520." By completing parts procurement and assembly within China, it achieves an astonishingly low price despite using a dual gear pump type for the discharge mechanism. By separating the workstation and melter, it also allows for customization, such as adding an injection nozzle. 【Features】 ■ Supports large area products ■ Low cost ■ Uses reliable OMRON products for PLC/HMI ■ High layout flexibility *For more details, please refer to the PDF materials or feel free to contact us.

The RNP-45 is a surface mount power film resistor designed to be compatible with the TO-252 package, weighing only 0.33 grams, with a thermal resistance of 3.0°C/W and a rated power of 45W. The resistive element is a pulse-resistant thick film, featuring excellent high-frequency characteristics with a reactance component of 2.7pF and 14.7nH, while also having a pulse power performance of 1kW-1µs despite its small size. The operating temperature range is from -55 °C to +175 °C. Additionally, it incorporates several design features, such as the removal of the metal flange to maximize the thermal performance of the resistor, compatibility with standard reflow SAC solder joints instead of wire bond connections, making it suitable for automatic mounting, an increased resistive element area to enhance surge performance, and the adoption of a 0.8mm substrate to strengthen bending stress.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.

Hotron's vehicle detection sensors allow you to search for products that meet your needs in three categories: "Purpose of Use," "Location of Use," and "Product List." The sensors detect the passage of vehicles, alerting you with rotating lights or switching the display of parking availability. They manage vehicle presence, full parking, and exit warnings in parking lots, contributing to safe driving and smooth operational management within the parking area. They are used in various settings, from coin-operated parking to large-scale parking lots.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
