The invention provides a
pressure injection method for integral forming of a non-pneumatic tire. The method includes the following steps that firstly, configured raw materials for manufacturing the non-pneumatic tire are placed into a
material storage box and are evenly stirred; secondly, the temperature of a pre-heating
pressure injection machine is raised to 180-190 DEG C; thirdly, pressure of the pre-heating
pressure injection machine is increased to 50-60 Pa; fourthly, the material inflow speed is adjusted to 10-20 m / s; fifthly, the pressure
holding time is adjusted to 2-3 min; sixthly, the raw materials for manufacturing the non-pneumatic tire in the first step are injected into the pressure injection
machine, and operation is started according to a preset mode; seventhly, after mold
assembly, injection, hot melting, cooling and mold disassembly are sequentially performed, the non-pneumatic tire is obtained. The technology is simple, multi-time
machining is not needed, one-time forming is achieved, operation is convenient, and cost is low; the obtained non-pneumatic tire is uniform and reasonable in structure and is not divided into an inner tire and an outer tire,
friction force and resistance between the inner tire and the outer tire are eliminated,
dynamic balance is good, and the non-pneumatic tire is resistant to abrasion and rolling and durable.
