Main Features

⑴ The product specifications are highly adaptable. Various products with extra large, extra small, extra thick and extra thin can be manufactured by plastic molding method. The sheet can be as thin as 1~2MM or even thinner. The product area can be as large as 10 ㎡, as small as several square millimeters, and the wall thickness can be as large as 20mm, as small as 0.1mm.

⑵ products have a wide range of applications. Daily necessities blister packaging, hardware blister packaging, automotive products blister packaging, electronic products blister packaging, food blister packaging, cosmetic blister packaging, computer peripheral equipment blister packaging, toy blister packaging, sporting goods blister packaging, stationery blister packaging and other

(3) equipment investment is low

(4) mold manufacturing is convenient, (plaster mold, copper mold, aluminum mold ~ ~ ~ ~)

(5) higher production efficiency.

(6) Save raw and auxiliary materials, light weight, convenient transportation, good sealing performance, and meet the requirements of environmental protection and green packaging; It can pack any special-shaped products without additional cushioning materials; The packaged products are transparent and visible, beautiful in appearance, easy to sell, and suitable for mechanized and automated packaging, convenient for modern management, saving manpower and improving efficiency

thermoforming common plastics and performance

plastics can be divided into two categories: thermoplastic plastics and thermosetting plastics according to their heating behavior. The materials used for thermoforming are mostly thermoplastic materials.

The single-layer or multi-layer composite plastic sheet (plate) used for thermoforming must have the following process properties

1. Plastic memory

2. Hot stretch

3. Thermal strength

4. Molding temperature

Thermoforming common plastic

1. PVC (characterized by less impurity content, better transparency, lower price, good dielectric properties, flame retardancy and self-extinguishing)

II. PP (rich sources, cheap, excellent performance, a wide range of uses.

1. Low density (PP is colorless, odorless, tasteless, non-toxic, flammable, white in appearance and density of 0.90~0.91g/㎝ 3.)

2. Good mechanical properties PP has especially good rigidity and extensibility, good stress cracking resistance

3. Good heat resistance

4. Good chemical stability

5. Good transparency, water resistance and water resistance

6. Strong processing and molding and usability

3. PE (is the largest production, one of the most widely used plastic varieties, odorless, tasteless, non-toxic, flammable)

four. PS (Plastic is hard, brittle, transparent, has no odor, emits black smoke when burning, is easy to dye and process, has low moisture absorption, dimensional stability, good electrical insulation and thermal insulation.)

1. High transparency and gloss

2. Excellent colorability and sanitary performance

3. Excellent dielectric performance

4. Excellent molding performance

Deficiencies:

1. Brittleness

2. Poor heat resistance

3. Moisture resistance, poor oxygen resistance

5. ABS (Opaque, Non-toxic, Odorless)

VI. PET (colorless, odorless, tasteless, non-toxic, excellent transparency, excellent mechanical strength, wear resistance and electrical insulation properties, good creep resistance, rigidity and strength. Excellent hygiene allows it to directly contact food)

Basic method of thermoforming

There are many methods of plastic thermoforming, which can be divided into two categories: molding and differential pressure molding according to the molding power. According to the molding die, it can be divided into single male mold, single female mold, mold-to-mold, no mold and other methods

molding, also known as mechanical stretch molding, is a molding method in which plastic sheets are molded into various parts in the form of single mode or mold-to-mold with the help of additional mechanical pressure or self-weight. The male mold refers to the shape of the mold is convex, and the female mold refers to the shape of the mold is concave. The mold only forms one side of the product, and the other side is exposed to the air. It is different from the pressing molding of a molding process. This method is basically applicable to all thermoplastics.
