12 chamber pneumatic needle valve hot runner preform mold

12 chamber pneumatic needle valve hot runner preform mold 1. Provide molds with ordinary structure and double cone self-locking structure. 2. The number of preform cavities can reach 48. 3. The preform is designed with computer simulated tensile testing to ensure the yield of blown bottles. 4. Adopting the world's advanced two-stage double taper positioning technology, each cavity is independently self-locking with a concentricity of ≤ 0.08MM. 5. The mold cavity and core are made of imported mirror corrosion-resistant plastic mold steel from Sweden (S-136) or Germany (2083), with a hardness of up to HRC50 and a long service life. 6. The threaded mouth is manufactured according to international standards, using imported nitriding steel with a hardness of up to HRC55 and a long service life. 7. Advanced design of hot runner, single point temperature control of nozzle, uniform heating temperature, improves the quality of plastic products. 8. No need to cut the gate, ensuring fully automated production of the mold and reducing labor costs for workers. nine The lifespan of the mold is guaranteed to be over 2 million mold cycles.
