Main mould components (die core, die cavity, screw neck) are made by injection process, and the material of which originates from Sweden high-quality mould steel (HRC 45). In this way, it is no doubt that the mould can be used for 2 million shots without any maintenance, meanwhile, the wall thickness between max. Part and min. Part is not more than 0.10mm; Turning center processes make sure that every parts can match well; Proper distribution of cooling water way improve productivity effect and molding cycle only takes 15 seconds( need proper water chiller, bottle design and injection machine)
2. Our mould, designed and developed by our engineers, is of high precision and long life span without traditional problems. In a word, Preform wall thickness is on error of 0.10mm; Weight difference is less than 0.3G; 2-5 moulds per minute; Utmost 144 cavities in one mould.
Main feature:
Cavity from 1 up to 144.
Control system with simulating stretch testing improve rate of production.
3. Adopt world advanced dipole taper localization technique, each cavity self-clamp independently, ensure mould concentrically.
4. Material of mould die core and die cavity are made of Sweden special mould steel.
5. Standard screw neck, imported nitride steel with high hardness is of long usage.
6. Advanced hot runner design and even heating temperature make sure the high quality of plastic products.
7. Valve gated type without tail reduces labor force.
8. At least 3 million shots guarantee.

Bearing rings: Dimension tolerance, geometric tolerances, and surface quality of bearing` s working surface will influent the operating noise. Naimei Bearing adopts precision CNC machining to dimension precision, geometric tolerances, design drawing, mold making, grinding, cleaning, assembly, testing, every link of strict checks, so as to ensure all our products are tested by our strict criteria.
Balls: The balls evenly with by the cage, often make rolling movement between 2 rings. The shape, size and number will directly influent bearing`s load tolerance and operating capability. We use high precision, small vibration steel ball. It`s surface must be strengthened, no bumps scratches, lacerations, pitting and notch.
Cage: Enclose and move with all or part of the balls. It also be used to insulate the balls, guide the balls` movement and to improve lubrication performance inside the bearing., etc. Naimei Bearing`s cage is commonly made of cold rolling carbon steel. But in the corrosiveness environment, nonparallel or high-speed situation, stainless steel, engineering plastics cagecan be decided on request.
Seal: Naimei Bearing adopts different kind of seal material to meet the requirement of their operating in high temperature and being compatible with grease. Acrylonitrile-butadiene rubber is our standard material. but in high temperature environment ,often adopt fluorocarbons, silicone , PTFE shield.
