■ Full automatic CNC ring die drilling machine is applied. The whole ring die processing is fully automatic controlled, and the holes of good smoothness are shaped at a time
■ Vacuum heat treatment technology reaches the most suitable working condition, which ensures the stability of ring dies.
■ Smooth holes make sure that pellets are of high output and quality.
■ Long working life
■ Different types and hole diameters can be processed.
Quality measurement of thermal treatment
■ Hardness
For each ring die, after thermal treatment, at least 8 points shall be measured on both sides of the ring die and inner circle surface by sclerometer. The surface hardness shall be as follow: stainless steel: HRC52-55, alloy steel: HRC60-62; the differences between each points shall be no more than HRC3.
■ Surface quality
Ring die surface shall be much smooth after being vacuum heat treated.
■ Roughness of holes
Check roughness of holes by comparing the roughness of samples.
■ Microstructure after quenching
Observe the microstructure of material by metallographic microscope, and the microstructure shall be martensite + carbide + retained austenite.
■ Ring die deformation
Tiny deformation will occur after being heat treated by vacuum hardening. Measuring tools shall be applied, and make sure dimension variation range shall be +0.5~1mm.
Dies-steel mould
Our dies are manufactured in the following steels:
■ X46Cr13 (i.e."stainless" steel or "chrome-steel")
■ 20MnCr5 (i.e."alloy" steel)
■ 18NiCrMo5 (i.e. similar to 20MnCr·5 but with a higher alloy content).
The X46Cr13 steel dies are vacuum / through hardened. The heat treatment achieves 53-55HRc hardness on the surface and in the core. The high chrome content makes it corrosion resistant. Although it costs more than a normal alloy, X46Cr13 is by far the most common material used through out the feed milling industry.
Dies made in 20MnCr5 and18 NiCrMo5 steel, on the other hand, are case hardened to obtain 60-62HRc hardness for approximately 0.8-1.2mm. Under the case hardened layer the steel remains malleable and therefore less brinle. The dies made of this steel are more resistant for pelleting extremely difficult fibre-rich products such as beet pulp, alfalfa, straw and hay.
Dies-perfect drilling
FDSP dies have an extremely precise and regular perforation: the "honey comb" layout of the holes is faultless.
Deep hole via gun drill drilling: ring die holes array evenly, uniform wall thickness between holes, to ensure ring die works successfully in pellet mill with smooth surface of pellet. It is important to upgrade smooth and polish level of ring die holes in order to decrease temperature difference, lower energy consumption, raise capacity, and reduce loss of nutrition FDSP reach international advanced level relate to hardness of ring die, evenness and smoothness of holes.

We can design project planning solutions according to the different needs of customers, and provide 3D renderings to enhance the user experience.Also, we' ll help customers to accurately sort out their own needs, and work with customers to repeatedly rationalize the scientific process, scientific, and optimize the design of the product system, and meet the reasonable individual needs of customers at any cost.With the spirit of perfectionism, we will build a good friend turnkey project, seek for our customers' value, and use the "differentiated competition strategy" to improve the market competitiveness for our customers and achieve strong cooperation and common development.
We design comprehensive solutions for feed machinery, fertilizer machinery, biomass machinery, storage machinery and engineering according to different requirements of customers, different raw materials and different sites.Our professionals will go deep into the construction site and plan well. In practice, it is truly tailored to local conditions. Different design schemes and construction methods are adopted according to different survey results to ensure scientific, reasonable, economical and practical, and environmentally friendly and then create a safe, efficient and stable production line for customers.
The company has a professional technical team with 25 years of practical experience in design, manufacture and installation. We persist on unified management, unified training, high quality personnel and good service always the same. Strict technical assessment is carried out every year, and the examination and approval is basic qualified for employment. Our workers have rich professional quality and high sense of responsibility for on-site installation and maintenance experience.With a high degree of professionalism, we help our customers achieve production efficiency in the shortest period of time, allowing customers to seize market opportunities and win at the starting line.
Regardless of pre-sales or after-sales technical support, we are always ready to provide customer satisfied service.With the rigorous order to ensure the highest efficiency, we are prepared to receive customer technical inquiries at any time, on-site service, equipment maintenance, production failures, service complaints and other issues to improve customer satisfaction.Through telephone consultation and on-site service, we can find problems and solve problems in time to ensure customer rights, provide professional and targeted services for different users, and escort customers throughout the process
After the installation and commissioning is completed, we will provide one-to-one technical guidance according to the actual situation of the customer, and will be responsible for training the operators until the customer can completely operate the production. We truly be "customer-centric" to provide excellent service to customers.Follow-up questions will be answered by professionals and they make timely feedback records, and provide solutions to problems. If there is a need for on-site guidance, depending on the specific circumstances, the company will arrange relevant professionals to provide timely guidance to the designated location.
In the service quality control, we insist on lifelong service and infinite improvement. In addition to the shelf life, we provide lifelong service to our customers. As long as the equipment is in use, the service of the good friend will not be terminated. In the service, we insist on the first time response, the fastest speed to solve the problem. At the same time, the product dynamic improvement system is established, and the typical problems on the products reflected by the customers are solved. Immediately after the solution, the product design is improved. According to the idea of 'no best, only better', we pursue endless improvement on the product, the service process on the issue. After the solution, we will immediately improve and optimize the service process, service standards and documentation system, and infinitely improve the service system with the spirit of 'accumulating the tide and dripping through the stone'.
