Product Details
Screw is the key component in plasticized parts, which is in direct
contact with plastics. Plastics through the effective length of the
screw groove has a long thermal history. It has to undergo the
transformation of three states (glass, viscoelastic and viscous
flow). The length, geometric shape and geometric parameters of each
functional section of the screw will directly affect the conveying
efficiency and plasticized quality of plastics, and will ultimately
affect the injection molding cycle and products. Quality.
Injection screw can be divided into general screw and special screw
according to its adaptability to plastics. General screw, also
known as conventional screw, can process most thermoplastic
plastics with low and medium viscosity. Crystalline and
non-crystalline civil plastics and engineering plastics are the
most basic forms of screw. Correspondingly, there are special
screw, which is used to process Plastics difficult to process with
ordinary screw, such as thermosetting plastics, polyvinyl chloride,
PMMA screw with high viscosity. According to the screw structure
and its geometrical shape, it can be divided into conventional
screw and new screw. Conventional screw, also known as three-stage
screw, is the basic form of screw. There are many new types of
screw, such as separate screw, split screw, corrugated screw,
transverse screw, non-metering screw, two-stage chlorine removal
screw, strong mixing screw and so on.

marrow of the trade gained and through years' accumulation, the
company has made constant innovation to ensure the machine
quality.Parts built into the machines of defferent mold locking
forces are all processed under specialized management. HJF series
injection molding machines are developed by Haijiang Company on the
basis of a collection of the advantages assimilated from all world
famous brand machines with optimized design realized by
CAD/CAM/CAPP where technical problems such as noise of the entire
machine and low energy dissipation are removed and thus the design
quality of products is secured. The company adopts advanced
equipment and technology and applies scientific management.
Besides, it has introduced high-precision full automatic CNC
machines fitted with imported electric and hydraulic parts, which
have tremendously improved the accuracy and steadiness of the whole
machine. Its present products such as HJK and KJF series and widely
applied in the electronic, automobile and civil industries.
In order to participate in competition in the world market,the
company has clustered a group of high quality technical and
managerial personnel with innovative spirit by means of optimized
combination fo personnel. The company faces the society and users
by acting on the principle of pursuit for ?rst class and sincere
