The main parameters for the equipment:

Equipment strengths:

• The equipment has the function of continuous heating at break point, automatic dewaxing function, wireless remote diagnosis function, and low temperature test function;
• The equipment vacuum main pipeline and dewaxing system are equipped with filters (patented products) to prevent dust and impurities from polluting the pump oil, and extend the oil change time and the service life of the pump unit.
• Convenient and intelligent: The control interface of the sintering furnace can be monitored through the mobile phone, and the operation status of the equipment can be controlled and understood anytime and anywhere. Fully automatic one-key operation function, one person can supervise multiple devices, intelligent production, and can be connected to ERP management system.
• Complete after-sales service system: provide 7×24 hours telephone hotline. After receiving the customer's fault notification, a solution will be proposed within 2 hours, and if it is urgent case which needs on site maintenance, technical crew will arrive within 12 hours after boarding the plane. With experienced professional after-sales service personnel, they are not only responsible for the installation and commissioning of the company's products, but also complete the after-sales and maintenance of sintering furnaces for both domestic and foreign manufacturers.
• Convenient service: Users can test products at the site of Ruideer if they have needs. The company's production site has conditions for hot pressurization.
• Quick installation: Under the condition that the user's water, electricity, and gas are in place, installation, debugging, and production can be completed within 20 days.
• Company testing equipment: In order to ensure the quality of the products, Ruideer is equipped with imported helium mass spectrometer leak detectors, which are used to test the sealing surfaces of the equipment before leaving the factory to prevent small leaks and achieve a perfect sealing state. At the same time, it is also equipped with cobalt magnetometer and coercivity magnetometer professional precision testing equipment (currently the sintering furnace equipment manufacturer, only equipped by Ruideer), to meet customers' rapid pre-acceptance at the production site, and to control the sintered furnace The sample block is tested, and the performance results of the furnace control plate sample block can be tested in time, and the detection level has reached the standard of a small and medium-sized alloy factory.

Vacuum system:

The vacuum system is composed of a series of components that make the furnace body a vacuum environment, mainly including:

• High pressure main valve: Pneumatic flapper valve

• Main valve of vacuum pipeline: Pneumatic butterfly valve

• Vacuum pipeline bypass control valve : PID control, pneumatic ball valve, parallel to the main valve, can automatically control the valve opening, and control the absolute pressure or vacuum in the furnace during the sintering process

• Filter: Contains 3 replaceable filter elements

• Roots pump

• Backing pump

• Air Ballast Valve : electromagnetic valve

• Nitrogen protection valve: electromagnetic valve

• Electromagnetic safety valve

Dewaxing system:

Dewaxing systems can be custom designed for customers. Whether customers use PEG, paraffin or other forming agents, they can be effectively removed and collected by condensation. Customers can choose positive pressure hydrogen dewaxing or negative pressure argon dewaxing according to the process. The dewaxing system adopts directional dewaxing, and uses air flow to control the pressure difference inside and outside the graphite liner, so that the molding agent enters the dewaxing system through the established pipeline to condense.
