Heat treatment by Ourself
As we all know, heat treatment is very important in the screw production process. In order to ensure the quality of products, Joiner has purchased professional heat treatment equipment to produce, so that we can control the construction process by ourselves. In China, we are the only company that does heat treatment by ourselves, and the heat treatment of screw components made by Nanjing factory is processed by outsiders, so the quality of products can not be completely guarantee.
Our strengths are based on many years experience supplying the following:
* Competitive costs per unit of production
* Fast turn round for collection and delivery on refurbished parts
* Parts available from stock for a wide range of extruder makes
* Comprehensive inspection procedure on all parts prior to dispatch
* A time proven quality service
* Latest manufacturing techniques and metallurgy, ensuring consistent and reliable performance of parts
* Customized solutions to meet specific needs.
