As one of the plastic products with the largest output and sales volume, the demand for blow molding processing has gradually increased with the continuous progress of society. What are the application scenarios of Blowing machine products today?
● The cost of Blowing machines (especially blow molding molds) is relatively low. For example, when molding the same products, the cost of Blowing machines is about 1/3 or 1/2 of that of injection molding machines.
● Blow mold materials have low toughness, simple structure, higher hardness than ordinary materials, and higher toughness to chemicals.
● Chromium plating on the mold cavity of the blow molding mold improves the hardness, makes the edge of the mold cavity chrome plated, and also makes the cavity surface of the mold cavity rough.
● The temperature control of the mold temperature of the blow molding mold should be uniform. The blow molding process can be divided into four stages, namely, mold closing, shear mold filling, temperature control, and mold temperature automatic control.
The mold temperature refers to the degree of melt rheology, which is due to the difference of rheological polymers, which will make the molecular chain reasonably fine.
● The mold temperature polymer cools the surface of the mold cavity, and sometimes it is also related to the cooling water. The cooling water is often room temperature, or the average cooling water at room temperature at high temperature.
● When designing leaking pipes, you will see that once overflow causes or overflow causes occur directly due to coolant.
● When designing leaking pipes, you will see directly due to coolant. In order to prevent this, a filter or filter screen must be set around the nozzle.
● When designing large threaded elements, melt the plastic with melted heat and extrude it from the nozzle of the Blowing machine. It will form the plastic effect of different sizes you want.
Note: This order stipulates that yellow materials cannot be used completely, and only the neck glue can be injected according to the requirements specified in the instructions.
● If phenolic resin is used, it is recommended to provide color according to the product to confirm whether the pigment has been fully molded and translucent;
● Liquidity. Monomer and fluidity refer to polymer mixture through flow restriction] or low speed and high speed mixing at VAC temperature;
● Status. Under dynamic working condition, the non-flowing resin can reach 1000mm in both directions, which is easy to operate.
● Oligomer distribution. According to the scope of application, the microscope can be summarized as 008 mm, which can highlight the melting point (specification), thus obtaining accurate color change.
Blended polyolefin is also called plastic melting point, tasteless and odorless. It is a fluid formed by the adhesion of powder melt caused by cyclic fluoroethylene and highly efficient thermal stability liquid.
What is the difference between HDPE, LLDPE, MDPE, HDPE, MDPE and polyethylene with the same molecular weight?
The blended PE element is a non-PE unit type, and is compatible with PP unit and PE unit.
Fluoropolymers of HDPE, LLDPE and polymers, such as GF/EVOH, Ala IG and Mil microparticles.
TPE, PA, EVOH, TPU, PBT, LLDPE, EVA, PAN, TPU, SEBS, and other general thermoplastics.
Supply of Unifiber (old hot cut) rust agent, handle strength, superior feel, comfortable feel, elastic feel, beautiful appearance and size.
CP series materials are dry, more comfortable, and shoes feel sterile, dry, time-saving and labor-saving. The core can compress strength.
PA, PP, PC, ABS, PBT, PET, PPO, PSU, POM, PMMA, PC anti tip foam.
PE, PVC, PSU, POM, PVC carbide, flame retardant, PPO, PP fireproof materials.
Engineering plastics such as Hypet, AS, PA, PBT, PVC, PPO, PSF, PE, PP are raw materials, and PEEK resin is used as additive, which makes them reach quite high quality.
The basic components of twin-screw granulator: barrel, screw, head, screw element, barrel, reducer, sensor, etc. Barrel part: host part: barrel, screw, barrel, flange, motor, rubber, etc.
