》Product surface weld line
valve sequential control injection can eliminate the product surface weld line.
Product standard
1.Zhenxiong adopts integrated time schedule controller with two working modes, diverse signal types and accuracy of 0.01s
The material import
2.The valve guide bushing and valve needle are custom made by Punch. The sealing element is imported from Switzerland, high temperature resistance,
oil resistance, stable quality.
3.Technology standard
3. The solenoid valve is imported from South Korea YPC, with stable quality, sensitive response, reliable quality and durability.
The sequence of valve sequence injection can eliminate the weld line on the surface
of the product.The sequence of 4-point valve in this product can control the glue injection ,
with G1 normally open, G2 delay of 0.9s, G3 delay of 1.32s, and G4 delay of 1.86s
The sequence of valve injection can eliminate the wield line on the surface of the
product.The sequence of 3-point valve in thisproduct can control the injection .
The G1 and G3nozzles will be opened when the G2 hot nozzles are filled to 1.6s.
》Reasons for system leakage.
■ Zhenxiong manifold is inserts and polished by the runner polishing machine
Along with Hot fit application (interference fit) without leakage .
Leakage of nozzle sealing
■ Zhenxiong has strict testing training and requirements for all the installation
personnel. Only when all the dimensions are processed accurately according
to the drawings can they be installed to ensure no leakage.
Nozzle and manifold matching surface leakage.
■ zhenxiong design has avoided possible machining errors, as shown in the
right figure
■ Zhenxiong focuses on engineering materials and high glass fiber products
Imported steel, specially treated, more wear - resistant and corrosion - resistant
■ Zhenxiong nozzles are made of imported steel with special treatment,
effectively ensuring the life of products. The quality of hot runner products is
designed with 10 years' service life, and the design life of products with fiber
added within 15% is designed with 2 million times of mold.

》Reasons for products yellowing ,black coating.
■ Dead angle existed in nozzle outlet .
Zhenxiong has professional MTO patent for molding transparent/color changing products nozzle.This type of nozzle
has no dead angle, fast color change and small pressure loss.
■ There is a dead angle at the corner of the manifold. The plug at the
junction angle of the runner adopts smooth transition, and the special
position adopts mosaic structure to ensure the junction angle is smooth.
■ The plastic material stays in the runner too long.

residence time
》Nozzle temperature difference accuracy
The internal temperature error of zhenxiong nozzle is no more than 10 degrees.
product standard
1. 90% of the products are standardized and 90% are in
sufficient inventory.
Standardized production ensures the consistency of quality.
2. Material import
Nozzles are made of ASSAB imported materials, and the
processing technology is strictly controlled to ensure the
interchangeability of
nozzles effectively.
3 .Process standard
The heating coil winding method has been tested strictly, the winding
process is standardized, and high quality is required to ensure stable
quality.
》Causes of wire drawing drooling of gate.
There is no reasonable cooling at the tip of the nozzle.
Reasonable cooling water line should be designed near the nozzle gate to increase
cooling Water line can avoid problems such as wire drawing and drooling caused by
heat accumulation at the gate
The nozzle selection is unreasonable
Zhenxiong nozzle is a special structure without nozzle core, without drawing and
drooling. Valve type nozzle is recommended for drawing caused by extreme injection
molding condition .
The temperature of nozzle is not stable and the long-term production stability is poor.
Zhenxiong heating accessories are imported , see the attached page
》Causes for valve needle stuck:
1. The valve needle is too long with the needle brush.
The matching length between the guide brush and the valve needle of zhenxiong
is shorter than other companies,which get less needle stuck.
2. Improper fitting tolerance between valve needle and needle brushing.
The matching tolerance between the guide brush and the valve needle of Zhenxiong
is customized according to the fiber adding material, and it has been tested and verified
repeatedly to ensure no leakage and needle stuck.
3. Processing error leads to unqualified or unstable quality.
