FAQ’s
What we can do
All your questions about the oil industry answered.
What materials are your blades and dies made from?
We manufacture blades and dies from a range of premium tool steels including D2, CPM IDV, CPM S390, M2, M42, and SS 420, selected based on application, polymer type, abrasiveness, and wear life requirements.
How do I select the right blade material for polymer pelletiser?
The correct blade material depends on the abrasiveness of the polymer, the presence of pigments or mineral fillers, machine speed, and environmental conditions. For standard polymers, D2 tool steel provides an excellent balance of wear resistance and toughness, while CPM grades are recommended for highly abrasive, pigment-rich, or glass-filled polymers. Concord Blades & Dies offers technical guidance to ensure the optimal material selection for each application.
What hardness levels are recommended for pelletiser blades?
Hardness is carefully optimized to maximize blade life while preventing chipping. Granulator blades are typically supplied in the range of 56 to 60 HRC for D2, 58 to 63 HRC for CPM grades, and up to 68 to 70 HRC for high-performance PM high-speed steels. Fixed blades are usually hardened slightly higher than rotating blades to improve cutting efficiency and reduce wear.
Do you manufacture custom blades and dies?
Yes, Concord Blades & Dies specializes in custom-engineered blades and dies. Products are manufactured to match specific machine models, cutting geometry, polymer types, and production requirements. Custom solutions help improve cutting efficiency, reduce downtime, and lower overall tooling costs.
What materials are used to manufacture industrial dies at Concord Blades & Dies?
Concord Blades & Dies manufactures industrial dies using premium tool steels such as D2, CPM IDV, CPM S390, M2, EN24, and stainless steel grades where corrosion resistance is required. Material selection is based on operating pressure, abrasion from polymer fillers or dyes, temperature, and expected service life to ensure reliable and consistent die performance.
What hardness levels are recommended for polymer processing dies?
Die hardness is carefully controlled to balance wear resistance and toughness. Most polymer dies are supplied in the range of 52 to 60 HRC, depending on material selection and operating conditions. Higher hardness is used for abrasive polymers, while slightly lower hardness is preferred where impact or thermal cycling is present.
Do you manufacture custom dies and provide technical support?
Yes, Concord Blades & Dies specializes in custom-designed dies manufactured to customer drawings or application requirements. The company also provides technical support for die design optimization, material selection, and performance improvement to help reduce downtime and extend die service life.
Can industrial dies be refurbished or reconditioned?
Yes, industrial dies can be refurbished through precision grinding, polishing, and heat treatment when required. Reconditioning helps restore performance, extend die life, and reduce overall tooling costs without compromising dimensional accuracy or processing efficiency.
