Typically, locating pins are used for controlled, fine tolerance positioning of a work piece. For example, a pallet that is moved along one axis, where the drive mechanism is not accurate and stable enough to place it in a position sufficiently accurate to execute a particular process, the use of locating pins may be the best solution. Usually two locating pins are enough to properly locate the work piece on one plane.

Mingrui Ceramic now offers a full line of standard and custom-made ceramic locating and welding pins. Advanced ceramics, which ensure a perfect fit for sheet metal and nuts and are subjected to temperatures of up to 600 °c, have long replaced metal in the production of welding pins. Metal cannot compete with ceramics with regard to insulating properties, resistance to temperature change, and minimal wear and tear due to the high degree of hardness and durability. Yet another advantage of ceramics is their smooth polished surface, which prevents welding spatter from adhering.

Main Features:

1) High hardness.

2) High heat resistance: alumina ceramic has excellentthermal stability,which means that it is widely used in areas where resistance to high temperatures is essential.

3) Good wear resistance: alumina ceramic is the material of choice for alumina wear parts.

4) High electrical resistivity: alumina is an electrically insulating material.

5) High corrosion resistance: it is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.

FAQ :

Q1: What are advanced ceramics? >>> Advanced ceramics - also referred to as engineering, structural or technical ceramics - have been processed to be very pure and, in general, have superior properties to unrefined ceramics. Many are man-made, i.e. they do not occur naturally, e.g. silicon nitride, and their properties can be enhanced to produce very high strength at high temperatures, good corrosion resistance, etc. Q2: What types of ceramic do you supply? >>> Alumina in purity from 90% to 99.7%, yttria stabilized zirconia (Y-PSZ), hot pressed boron nitride, machinable glass ceramic, boron carbide, silicon nitride, mullite and cordierite. Q3: Can I machine the ceramics myself? >>> The harder ceramics like alumna and zirconia will require diamond tooling but other materials like Machinable Glass Ceramic and Hot Pressed Boron Nitride can be machined. To get the right result it does take time, experience and semi-specialised tooling but it can be done and many of our customers take advantage of this when they need extremely fast solutions in-house. Q4: Can I get a sample or purchase a small quantity? >>> Yes, we are happy to supply small samples of material for you to test. We can also supply prototype quantities through to volume production to suit your needs. Q5: How long will it take for you to send me a quote? >>> This depends totally on the complexity of your requirements. For simple items such as bars and rods, we can generally supply a quotation within 24 hours. Q6: What's the delivery time? >>> For our standard products, like ceramic protection tubes and insulating rods, delivery time is normally 7 working days. For hot pressed boron nitride and machinable glass ceramic, it's about 10 working days. For customized products made of alumina, zirconia, boron carbide and silicon nitride, total producing time is about 30 working days.
