Problems solved by technology

The above-mentioned process has the following disadvantages: first, the end-to-end connection of long strips of fluororesin film will inevitably form a joint seam, and the edge will be unevenly stressed and easy to disengage, which requires high technology and affects the appearance; second, During the hemming process, wrinkles will inevitably form on the edge of the fluororesin-coated fabric. If it is a round fluororesin-coated fabric, there will be many wrinkles. These wrinkles waste fluororesin raw materials and affect the appearance of the product.

Embodiment 1

[0039] Embodiment 1: With reference to Figures 1 to 5, the fluororesin seamless film encapsulation method in this embodiment includes the following steps:

[0040] ①Put the fluororesin raw material into the mold, and add a coloring agent of 1 to 5% by mass to the fluororesin raw material. The coloring agent is high temperature resistant and consistent with the color of the fluororesin coating base fabric. It is obtained by one of the following methods Cylindrical body 1, as shown in Figure 1:

[0041] The first type is holding pressure, demoulding, and finally sintering the molded castings. The nominal pressure of holding pressure is 200~300kg / cm 2 ;

[0042] The second type is mechanical injection;

[0043] The third type is mechanical vulcanization;

[0044] ② Cut the obtained cylindrical body 1 into a ring 3, the axial thickness of the ring 3 after cutting is 0.1-0.3mm, and an annular gap 31 is cut on the inner wall of the ring 3, as shown in Figure 3;

[0045] ③ Cut the fluororesin-...

Embodiment 2

[0049] Embodiment 2: Referring to Figures 6, 7 and 8, the fluororesin seamless film encapsulation method in this embodiment includes the following steps:

[0050] ①Put the fluororesin raw material into the mold, and add a coloring agent of 1 to 5% by mass to the fluororesin raw material. The coloring agent is high temperature resistant and consistent with the color of the fluororesin coated base fabric 2. After one of the following methods Obtain the cylinder 1:

[0051] The first type is holding pressure, demoulding, and finally sintering the molded castings. The nominal pressure of holding pressure is 200~300kg / cm 2 ;

[0052] The second type is mechanical injection;

[0053] The third type is mechanical vulcanization;

[0054] ② Cut the obtained cylindrical body 1 into a ring 3, and the axial thickness of the ring 3 after cutting is 0.1~0.3mm, as shown in Figure 6;

[0055] ③ Cut the fluororesin-coated base fabric 2 into a shape that matches the ring 3, and then take the cut fluorore...

Abstract

A fluorine resin seamless film edge packaging method is characterized by including the following steps: 1, adding the fluorine resin raw material in a mold, obtaining a tubular body by one of the following modes: firstly, pressure maintaining, mold stripping and finally sintering the compression molding cast, secondly, mechanical injection; thirdly, mechanical sulfuration; 2, cutting the obtainedtubular body into a ring, and cutting a ring crack on the inner wall of the ring; 3, cutting the fluorine resin coated backing into a shape adapting to the ring, and then inserting in the crack of the ring; 4, obtaining the seamless wrapped fluorine resin coated backing after heat pressing. Compared with the prior art, the advantages of the present invention lie in that: there is no connection seam after wrapping, the wrapping has uniform force and is difficult to come away, the invention has lower process requirements; simultaneously crumple will not occur, and the products has comparativelyaesthetic overall appearance without seams, crumples and junctions.

Description

Technical field [0001] The invention relates to a seamless film encapsulation method, in particular to a fluororesin seamless film encapsulation method. Background technique [0002] Most of the cooking tools used in the cooking industry in European and American countries are fluororesin (Teflon) pans and non-stick pans with non-stick metal coatings. Using natural gas or gas to heat cooking food is very easy to cause the bottom of the pot to be overheated and burn out the non-stick fluororesin coating (Teflon) to produce poisonous gas, causing food poisoning, affecting people's health, and being burned out The pot cannot be reused, which brings about waste of resources and environmental protection. On the other hand, with the rapid development of baked household appliances, it is more convenient for people to cook food processing, such as microwave ovens, toasters, electric ovens and so on. In order to achieve more hygienic, more time-saving, more convenient cleaning, more beau...
