Product Description:


Aluminum Stretcher

1.The function of this equipment is to straighten the extruded profiles, prevent secondary deformation.


2.Push force:15T-400T


3.According to the difference of stretcher jaws-clamping, it has three types: manual jaw-clamping, pneumatic jaw-clamping, hydraulic jaw-clamping.


4.The stretcher is designed to be anti-pulling type, the push force varied from 15T to 300T, above 300T stretcher can be done as per customers' requirement.


120T-6000T aluminum straightening machine

Straightening machine action is aluminum plate, bar extrusion, rolling and leveling quenching or other processing step, the unevenness extends to the internal stress generated when the value reaches a certain level, will result in a plate shape buckling or wave-shaped, plate-shaped stretch leveler improvement is the use of the existence of the internal stress of the aluminum plate, bar straightening device by stretching stretch beyond the yield point of the product, causing permanent deformation approach, eliminate stress prevent secondary deformation. The principle is the use of the material is not necessarily a straight longitudinal fibers when its choppy, but choppy plastic fibers are stretched in order to achieve equal length, the force is bound to remove substantially equal amount of rebound back to the steady state of the phenomenon to achieve the purpose of straightening. After further processing aluminum can or chemical milling no longer cause deformation. The device implements automatic tension control work, the main hydraulic system enables automatic pressure relief, after setting the amount of stretch, stretching to reach the amount of stretch function automatically stops stretching, stretching basically achieved under normal circumstances without operator intervention, so that tension leveler is simple, powerful, good stability.

Q:What is the delay time of the packer's cross sealing?
The sealing time is how long the delay is when the sealing dies are joined together.
Q:How does the pulp solidify? What additives do you need? Curing agents? Or what do you need as binders?
Urea formaldehyde resinUre-aformaldehyde resinsUrea formaldehyde polymer. Also called urea formaldehyde resin. The cross-linking English abbreviation UF. molding, the product is insoluble and infusible thermosetting resin, urea formaldehyde resin cured phenolic resin than the color of light, translucent resistance, weak acid and weak alkali, good insulation properties, excellent wear resistance, low price but, in case of strong acid and strong alkali decomposition, weather resistance is poor. The name Beetle. urea and 37% formaldehyde aqueous solution can be obtained by the polycondensation of linear urea formaldehyde oligomer in catalytic acid or alkali industry, with alkali as catalyst, reaction temperature of about 95, the molar ratio of formaldehyde to urea as 1.2.0, to ensure that the resin curing reaction. The first step to generate and dimethylol urea, then hydroxymethyl amino and soluble resin by further condensation, if by acid catalysis, easy to cause the product to be stored to gel. In neutral condition. The linear UF resin for ammonium chloride Curing agent can be cured at room temperature. The molding powder at 130 to 160 DEG C heat curing accelerators such as zinc sulfate, trimethyl phosphate, two oxalic acid ethyl ester can accelerate the curing process. The urea formaldehyde resin is mainly used in the manufacture of molded plastic manufacturing, daily life products and appliance parts, also can be used as adhesive, paper and fabric sheet the pulp, plywood, decorative board and so on. Because of its light color and easy coloring, products often colorful and magnificent.
Q:Hello, I just do packaging machinery, foreign trade, I do not know how to search customers ah.
If you have your own website here, through the optimization and promotion, to promote their products out, the customer concern, love content search, when people search through GG to see your home site, you may consult. There are many ways
Q:Food packaging process is not standardized, there is no responsibility?
Yes, automatic packing machine. I'm an employee of the automatic packaging machinery company.
Q:Color code positioning of packaging machinery
The use of the printed color packaging materials, photoelectric switch (available on the color electric eye tracking and positioning), through the control system to drive the stepper motor rotation and color according to the distance between the automatic stop, to complete and accurate packaging products logo.
Q:What does the mechanical equipment include?
Rail aligning machine, rail straightening machine, grinding machineSlag shaping machine for track flat car internal combustion engine
Q:The role of food packaging machinery
Packaging is the necessary condition for products to enter the circulation field, and the main means of packaging is the use of packaging machinery. With the development of the times and the progress of technology, packaging machinery is playing a more and more important role in the field of packaging. The main functions of packaging machinery are as follows:
Q:What is the name of the paper used in packing machine parts and yellow?
Rust preventive action, commonly used for steel vapor rust preventive paper, but also for a variety of metals.
Q:What machine does the packing carton machine have?
Do the carton machinery: corrugated production line / single machine, printing machine, polishing machine, laminating machine, mounting machine, die-cutting machine, book paste machine for package machinery: automatic sealing machine, automatic strapping machine
Q:What's the best place to use the pillow type packing machine?
This device is now relatively mature technology, but each manufacturer's design is still a little different
