Dyeing washable gasoline, dyeing alcohol, dyeing oil, dyeing pigment, dyeing tube, dyeing needle, bottom box, dyeing rod, dyeing screw, dyeing handle, etc.

PTFE (also known as polytetrafluoroethylene) is a thermoplastic plastic, polymerized from ethylene, which has high chemical stability, does not decompose when burning, and is conducive to processing and coloring. For example, ethylene and films, pigments containing ionic olefins of new grease before ethylene are called “ethylene compounds”, which are absorbed by ionic alkyl solvents and hydrochemical solvents after treatment. Before weighing, they are composed of ionic alkyl compounds according to the phase separation of the medium, that is, ionic alkyl cellulose or ionic olefin ester resin.

Near vacuum plasma contains air of solid, general oxidation resistance and surfactant, which is suitable for pharmaceutical, pharmaceutical and pharmaceutical industries.

The plasma PT molecular device is composed of a resin type atomic exchange oxygen sensor, compressor, launching equipment and plasma device.

The gas reactor is composed of pumps, electrochemical reaction tube control and gas resistant cone tube arrangement.

The PT lamellar reactive monomer can be mixed with three roll fretting heat and oxygen reactive ethylene (P-ion) gas membrane.

This composite film can be used for key processes of internal coating and thermal performance requirements at different temperatures, and is widely used for PT sheet coating.

Polyester film is used as polymer packaging material for mixing. Pet materials have great toughness and multipurpose durability, which means that they are more widely used in the outside world.

The printing method is a variety of printing units used for its materials, such as paper, printing sheet and composite film, which can mix different colors. Because of the special printing colors, the products have more colors and are widely used.

The corrosion resistance is poor. If it needs to be decomposed perfectly, it will cause acid, alkali and pigment pollution. No matter the paint surface, paper bag and other patterns, they need to be eliminated.

Shrinkage in pipe (cloth mouth), (60%), water or wet plastic water. The use of plastics with poor temperature resistance, preferably in a water vapor environment, is called corrosion resistant plastics.

Flow pattern: poor material fluidity, especially plastic materials. If we do not use it properly, the plastic bag will have a dent if it is within the wall thickness. Different structures of plastics at the same temperature may cause dents and dents.

Flowlines: Fill the cavity with special injection. It causes us to produce flow marks in the mold cavity. If we use a single injection, the defects can be eliminated when filling the cavity with this method. If we use hot runner, the cooling of the mold cavity should be better than the cavity temperature without setting the cooling medium. The location of gate is usually determined by gate size, surface area of mold cavity, surface area of injection mold cavity, material surface area and material surface area. If a non flowing cavity is used, it may show this condition. Please pay attention to the information about materials or injection mold cooling at any time.

From injection mold to injection mold, we quickly pay attention to mold manufacturers, injection designers, engineering designers, product design engineers, injection molding processing engineers, etc.

Closed systems such as small batch samples and molds with complex internal component structures can also become an urgent production efficiency. With the quality control requirements for PC parts, it is also necessary to be able to effectively control the production process parameters, achieve faster computer control, more flexible implementation and more accurate process.

On the one hand, injection molding needs to be debugged from the process level, mold design, mold manufacturing and production cycle debugging.

The management of technicians and process equipment must be practical and feasible, and the technical level must be improved. The existing technology formulation must start from the process level, but it still needs powerful technical equipment and technical equipment to meet the market needs.

On the other hand, injection molding processing must start from the process level. The design of process and plastic products at the process level must be clear, firm and tightly combined, and the extrusion coefficient tolerance should be appropriate. At the same time, under this condition, the plastic products should be pre tightened, without condensation, glue leakage, discontinuity, and dead corners. In order to avoid distortion and deformation, a degree of freedom is required for each additional wall thickness. The wall thickness should include the part with enough thickness. The wall thickness of this part is determined according to the deformation degree of the plastic products. Generally, the thickness of the part is 0.2 mm from the plastic to the uniform thickness.

The uneven wall thickness is mostly determined by the plastic. When the wall thickness exceeds 06mm, the plastic products are more likely to deform. The wall thickness uniformity is determined according to the deformation degree of the plastic. In addition to calculating its size, the molding pressure must also be calculated for the part of the design wall thickness. The wall thickness is generally taken as 0.5~07mm, or about 20 mm. The tolerance is 1/3 of the wall thickness.

● Tolerance: determine the wall thickness of plastics to avoid damage as much as possible. To reduce the bending rate, the material shall have a certain rigidity, the wall thickness shall not be less than 05, and the reduced concave angle shall not be greater than 15mm,

HIPS and viscose copolymer (PPH) are transparent amorphous resins, and their chemical structure allows: a). LDPE。

Plasticizer: reduce PPE copolymerized with viscose, BMC is generally improved if there is some, PE and other polymers are usually suspended on the fiber,

Plasticizers: Plasticizers can be mixed with plastics, paper, wood, leather and other plastic components. Plasticizers can be selected. Different plasticizers have different degradation effects, and are also applicable to rigid materials, such as injection molding, blow molding, tape casting film and other processes.

Zinc aluminum alloy and magnesium alloy: mainly used to manufacture magnesium alloy die casting moulds, zinc aluminum alloy die casting moulds, magnesium alloy die casting plants, zinc alloy die casting plants, magnesium alloy die casting plants and magnesium alloy die casting moulds.
