WO2004050336A1 - Method for producing hollow plastic articles - Google Patents

Abstract

The inventive method for producing hollow plastic articles consists in cutting off a hollow article when a blank is rotatable around the longitudinal axis thereof and/or an actuating device is rotatable around the surface of said blank. Said cutting-off is carried out at a temperature of 220-240 °C, a cutting off time of 1-3 seconds and with a speed of rotation of 2-3 rpm/sec. A drop-shape bulge is formed on a free end of an L-type rib simultaneously with said cutting off. A pressing on is carried out in two steps, i.e. at a longitudinal pressure of 0.6-0.8 MPa and a transversal force of 30-34N. In the first step, a closing element is bent towards the surface of a container in such a way that the drop-shaped bulge of the rib is encompassed. In the second step, the two-side sealed joint thereof is carried out.

A preferable embodiment of the method of working with the laser is laser radiation with a diameter of 0.3 mm.

It is possible to cut the blade at the same time as the rotation and the simultaneous melting of the border (at the expense of friction).

With this, it is possible to irradiate the boundary by cutting off, by carrying a clear character and without obstructions, mechanical discharges and tears.

BEST MODE FOR CARRYING OUT THE INVENTION.

The method of manufacturing the floor of plastic products as agreed to the invention is as follows:

It takes the purchase of a finished product (capacity) made from plastic, for example, from an electri- ethylene.

Then, it discharges the consuming part of the machine in the case of non-delivery of the goods to them without paying for the goods.

There is a capacity of all kinds of products, for example, 3 by any loose or any liquid substances, including food.

After that, it is supplied to the product in the presence of a sealant (sealant), a metallic closing sealant (jack) with a disconnector installed on it.

In the process of restoring, there is a reduction in the income from the production of its final product and / or reparation of the income from the business.

There is a temperature of 220–240 ° C, and a period of 1–3 sec. and the rate of rotation of the harvest - 2-3 s / sec.

At the same time, on the other side of the Larger part of the Republic, the result is a creep-like thickening.
