The production of the lost foam casting foam pattern (white mold) is the first process, and the shape, dimensional accuracy and surface quality of the white mold play a decisive role in the quality of the castings produced. The production of the lost foam pattern depends on the type of casting alloy and the structural… Read More »Lost foam casting white mold production line
As a tension control system for unwinding in the winding system, the magnetic particle brake can output a large braking torque and slip power when working, so it is widely used in web offset printing machines. During the production process, the magnetic particle brake can continuously adjust the tension of the paper in a large range to… Read More »Magnetic Particle Brake: Pros, 3 Types Troubleshooting
Precautions 1#: First time using Before using the magnetic particle brake for the first time, check whether the running part is flexible. If there is hysteresis and jamming, it may be due to the vibration during the transportation process, which makes the magnetic particle stagnate under the magnetic particle brake, causing the rotor shaft to fail to rotate.… Read More »7 precautions in the use of magnetic particle brakes
Both types of brakes are typically used for torque and tension control. The basic characteristics of magnetic particle and hysteresis brakes are very similar; torque is proportional to input current and independent of speed. The torque characteristics of both brakes exhibit hysteresis, which means the torque vs input current graph has two lines; one for… Read More »Magnetic Particle or Hysteresis Brakes: Which Works Better For You

Lost Foam Casting Raw and Auxiliary Materials There are many types of raw materials required for lost foam casting production, which can be roughly divided into model raw materials (foam plastics), coating raw materials (refractory binder), modeling raw materials (dry sand), and smelting raw materials (pig iron or other alloys). Whether the quality and parameters… Read More »Lost Foam Casting: Materials, Techniques, Equipment
Lost foam casting can be divided into self-hardening sand lost foam casting and binderless dry sand lost foam casting according to its mold material. According to the pouring conditions, it can be divided into ordinarily lost foam casting and negative pressure lost foam casting. 4 process classifications of the lost foam casting The foam plastic… Read More »Lost foam casting: 4 process classifications, 26 advantages

How to build precise unwinding/rewinding systems using simple, easy-to-use technology. Magnetic particle brakes can provide an adjustable braking tension for unwinding film, wire, or any web. Magnetic particle clutches can provide an adjustable tension for rewinding the same. Simple, effective tensioning systems can easily be built when each is teamed with a D.C. power supply… Read More »5 Keys of Tensioning with Magnetic Particle Brakes & Clutches
What is lost foam casting Lost foam casting, also known as full mold casting, is a new casting technology for precise molding. It is to bond and combines foam models similar in size and shape to castings to form model clusters, brush refractory coatings, and after drying, bury them in Vibration modeling in dry quartz… Read More »Lost Foam Casting: Basics, 6 Advantages, 12 Typical Castings
