Q:How are the birthday cakes wrapped? How do cake boxes shape?

I make the packing boxMay I have design draft?We make cake boxes, tooI'm doing it right now

Q:Ask some books about packing machinery. Especially about carton forming

Color box production processFirst, the printing press used offset printing to complete the printing of facial tissues.Two, paper by laminating machine or coated paper or polishing machine polishing, increased light, moisture.Three, the paper and corrugated cardboard laminator (by laminating machine) or adhesive glue machine.Four, through die cutting machine die-cutting.Five, the molding of cardboard with nail box machine or glue glued to the common carton.Six, ten or several bundles, send away.

Q:How does the pulp solidify? What additives do you need? Curing agents? Or what binders are needed? Will the curing process require high temperature or what?

The industry with alkali as catalyst, the reaction temperature of about 95, the molar ratio of formaldehyde to urea as 1.2.0, to ensure that the resin can be cured. The first step of the reaction and generate a dimethylol urea, then hydroxymethyl amino and soluble resin by further condensation, if by acid catalysis, easily lead to storage products need to gel. In the neutral conditions under the linear urea formaldehyde resin with ammonium chloride as 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 electrical components also can be used as adhesive, paper sheet and fabric size, veneer, decorative board and so on. Because of its light color and easy coloring, products often colorful and magnificent.

Q:How does the lost foam forming machine work?

The molding process consists of two stages, steam heating and cooling molding.After the pre curing beads by steam heating, about 20S-60S of the time, the air can overflow, produced after the expansion of the heated pressure, the pressure is greater than the sum of the vapor pressure bead outside of the heating, the polymer softening, foaming agent after vaporization bubble in pressure is greater than the outside pressure, bead again expansion, and a whole fullness bead gap, the formation of foam products with the same shape of the mold, cooling after molding can polymerization.

Q:How long is the distance between the molding machine and the roller in the vertical automatic packing machine?

This does not have any provisions, mainly sealed to seal, you can, in general, are in the 1CM or so

Q:Ask: how to improve the strength of PP sheet, used to absorb the molding of the coil, need to meet the requirements of food packaging, and food direct contact.

Change to copolymerization PP material, Nordic chemical, some brands are available

Q:Method for making carbon fiber model

A woven process in which all fibers are arranged in the same direction by three-dimensional braiding, and then each fabric is woven into a fabric in a direction that is cheap and interwoven at one angle. The two characteristics of this method are integrity and mechanical rationality. They are much better than traditional ones in shear strength, impact resistance and damage characteristics.

Q:Foam box production equipment, where is the production of seafood boxes, such as foam box machine?

(but the leadership of the company are basically old industry employees, so it can be said that the bridge industry is Great Wall Co mold center's predecessor) when just beginning to go to a month of military training, this is the the Great Wall tradition, basically can not be changed. Very tired drop! Just go, must be the next workshop, should be to stamping, the equipment is relatively old, is still very backward, can not be compared with the manufacture of three, let alone the new factory in Tianjin.

Q:Vacuum plastic forming process is a kind of thermoforming processing method

By means of the pressure difference or mechanical pressure on both sides of the sheet, it is deformed and coated on a particular mold surface, cooled, shaped, trimmed and trimmed

Q:What's the maximum size of the automatic packing machine?

For example, small piece of candy packaging than bread and packaging magazines, A4 paper, diapers or window etc.
