2. Product Description
GPO 3 CNC Machining Custom Slot Wedge is a necessary part of the machining process of motor windings. Its main function is to fix the coil embedded in the iron core to prevent its displacement in the slot, including preventing the coil from entering the slot or popping up. There are two types of slot wedges that are commonly used, one is insulating slot wedges that play an insulating role, and the other is magnetic slot wedges commonly used in high-efficiency and high-voltage motors. Our products are made of GPO3, which has good insulating properties, so it is safer to use. And this material is highly malleable and can also have different shades and shapes, so it can meet your various needs. In addition, our GPO 3 CNC Machining Custom Slot Wedge is CNC machined, so the production process is more automated, with greater precision and uniformity, saving a lot of time and labor costs.

5. FAQ
1. What is the different between SMC machining slot wedge and UPGM203 (GPO-3) CNC Machining Custom Slot Wedge?
A: SMC machining slot wedge is processed by SMC insualtion sheet and UPGM203 (GPO-3) CNC Machining Custom Slot Wedge is composed of unsaturated Polyester Glass Mat.Mechanical and electrical properties is different between these two kind of slot wedge.
2. What is the difference between FR4 CNC Machining and UPGM203 (GPO-3) sheet CNC Machining?
A: The main difference is price.FR4 CNC Machining price is much higher than UPGM203 (GPO-3) sheet CNC Machining.FR4 have the advantages of better tensile strength,wear resistance,high temperature resistance than UPGM203 (GPO-3) and SMC sheet.
3. Why choose UPGM203 (GPO-3) CNC Machining Custom Slot Wedge？
A:UPGM203 (GPO-3) CNC Machining Custom Slot Wedge is very comprehensive, so it is definitely the best kind of superalloy. Not only that, but also its service life is long. Therefore, for customers, choosing such high-quality products is more conducive to use, and there will be no problems in the process of use. Of course, the most important thing is that it can bring a lot of convenience to various industries, and contribute to the development of production. This is the most important reason why it is welcomed by people.
Secondly, insulating composites have strong moldability and good oxidation resistance. Therefore, it can be widely used in various industries, and plays an important role in industrial production. Without his participation, industrial production would be seriously affected.
4. Why does the price is different from different supplier of same profile?
A: Different suppliers have different specifications and sizes, and the product weight will be different,this will affect the profile price. In particular, different suppliers use different raw materials, resulting in a large gap in mechanical properties.
5. What is the temperature resistance grade of the GPO 3 CNC Machining Custom Slot Wedge?
A: The temperature resistance is F class of 155 centigrade(°C)
6. What is delivery time?
A: Our capacity is 30T per month and we will provide 15-25 days delivery time for different requirements.
6. Our Certificate
We have passed ISO9001 Quality Management Mystem, ISO14001 Environmental Management System, and our UPGM203 and SMC Insulation Sheet have certified by RoHS and Reach certification.
7. Our Overseas Exhibition
We actively participated in foreign related industry exhibitions, such CWIEME in Germany and Shanghai,AEC in France,Big5 in Dubai and Elecrama in India to bring our customers the best insulation products.
8. Packing and Delivery
We provide our customers with strong kraft paper and belt to ensure the safety of packing,also use PP film wrapped outside to avoid the damage and moisture in transit. We use wooden pallets with IPPC marks and fumigation certificate, which fully meet the importing countries crequirements.
