High-Temperature Casting Machine Designed for MC Nylon Casting
Adopts energy-saving heater system, solving the problem of easy oxidation and carbon deposition in traditional heat transfer oil channels, more eco-friendly.
This high-temperature casting machine is specially designed for the MC nylon casting process, using caprolactam monomer with sodium hydroxide and TDI as chain extenders to produce cast nylon parts. It is widely applied in mining and construction machinery (sliders, couplings, mixer gears), lifting and transportation (pulleys, rollers, support wheels), and general machinery (rollers, tubes, rods, shaft sleeves, bearing bushes, gears, worm gears, guide rails, piston rings, sealing rings, impellers, and pulleys). High-precision medium-low speed gear pumps with a metering accuracy of ±0.3% and 450℃ resistance ensure accurate material ratio and stable system pressure. An energy-saving heater solves oxidation and carbon deposition in traditional heat-transfer oil channels, while multi-point temperature control maintains ≤±2℃. The patented mixing seal prevents backflow and cross-contamination, delivering stable and reliable casting.
Working Principle
Raw Material Conditioning
Melt caprolactam monomer in the temperature-controlled tank with circulation pumps, and add sodium hydroxide catalyst and TDI activator based on the target formula.
Precision Metering
High-temperature gear pumps with servo drives deliver the exact flow rate according to the programmed ratio (A:B = 1000:1–1000:5), ensuring accurate material proportion.
High-Temperature Casting
The dynamically mixed material is cast into the preheated mold through the high-shear mixing unit, with patented sealing preventing backflow and cross-contamination.
Polymerization & Demolding
The cast nylon part polymerizes and cures in the mold through anionic ring-opening polymerization, then is demolded for post-processing and finishing.
Technical Specifications
Integrated multi-point temperature sensors and digital temperature controllers achieve automatic precise temperature control with temperature error ≤±2℃, featuring auxiliary heating and heat preservation functions, saving power and time. Equipped with isolation tank to protect vacuum pump, over-pressure alarm, and upper/lower temperature limit protection functions.
