Automatic EVA Foam Injection Moulding Machine for Making Slipper Sandal Shoe Sole Rain Boots in EVA Material

Electric Control Unit

Touch-screen human-machine interface makes the parameter setting fast and easy; electric cabinet is stand-alone to avoid malfunction caused by machine vibration.


Injection Unit

1. The injection system is optimized by a unique screw design with precise temperature control.
2. The repeatability is assured by the precise volumetric control and the proportional valves of pressure and flow.
3. Injection volume is sufficient to meet the production with multi-cavity molds.
4. Equipped with multi-zone thermal control on each injector. Each zone is set individually in accord with different characteristics of compounds and production conditions.
5. Precise transmission system with the sliding structure driven precisely by servomotor control system;  the movement of the injection unit is smooth, and the positioning is fast and accurate.


Mold-Holder Unit

1. To meet various productions, the mold-holder is designed to be suitable for different types of molds such as one mold one pair, one mold two pairs, one mold three pairs in small sizes.
2. The high clamping force of mold-holder is realized with hydraulic cylinders, which can automatically compensate the variation of mold thickness caused by temperature change.
3. The clamping system is equipped with two independent sets of cylinders at each station. The big hydraulic cylinders averagely distribute the high clamping force on the whole surface of the mold to avoid flash.
4. The mold open stroke is long to make collecting parts and cleaning mold easily.
5. There are independent temperature control units for up and down mold plates in each mold-holder.  The temperature of each mold is controlled with high precision to produce parts with stable quality.

Titanium Dioxide(TIO2)

Titanium dioxide is an important inorganic chemical pigment, the main component is titanium dioxide. The production process of titanium dioxide has two process routes: sulfuric acid method and chloride method. It has important applications in coatings, inks, papermaking, plastics and rubber, chemical fiber, ceramics and other industries.

It has two types: rutile type (Rutile R type) and anatase type (Anatase A type). The rutile crystal structure is compact, relatively stable, and has low optical activity, so it has good weather resistance, and has high hiding power and decolorizing power.

Titanium dioxide is widely used in coatings, plastics, rubber, ink, paper, chemical fiber, ceramics, daily chemicals, medicine, food and other industries.
The coating industry is the largest user of titanium dioxide, especially Rutile Titanium Dioxide, most of which is consumed by the coating industry. The paint made of titanium dioxide has bright colors, high hiding power, strong tinting power, low dosage, and many varieties. It can protect the stability of the medium, and can enhance the mechanical strength and adhesion of the paint film to prevent cracks. Prevent the penetration of ultraviolet rays and moisture, and extend the life of the paint film.
The plastics industry is the second largest user. Adding titanium dioxide to plastics can improve the heat resistance, light resistance, and weather resistance of plastic products, improve the physical and chemical properties of plastic products, enhance the mechanical strength of the products, and extend the service life.
The paper industry is the third largest user of titanium dioxide. As a paper filler, it is mainly used in high-grade paper and thin paper. Adding titanium dioxide to the paper can make the paper have better whiteness, good gloss, high strength, thin and smooth, no penetration during printing, and light weight. Titanium dioxide for papermaking generally uses Anatase Titanium Dioxide without surface treatment, which can act as a fluorescent whitening agent and increase the whiteness of paper. However, laminated paper requires the use of surface-treated rutile titanium dioxide to meet the requirements of light resistance and heat resistance.
Titanium dioxide is also an indispensable white pigment in advanced inks. The ink containing titanium dioxide is durable and does not change color, has good surface wettability and is easy to disperse. The titanium dioxide used in the ink industry has rutile type and anatase type.
The textile and chemical fiber industry is another important application field of titanium dioxide. Titanium dioxide for chemical fiber is mainly used as a matting agent. Since the anatase type is softer than the gold red type, the anatase type is generally used. Titanium dioxide for chemical fiber generally does not require surface treatment, but in order to reduce the photochemical effect of titanium dioxide and prevent the fiber from degrading under the action of titanium dioxide photocatalysis, surface treatment is required for some special varieties.
The enamel industry is an important application field of titanium dioxide. The enamel grade titanium dioxide has high purity, good whiteness, fresh color, uniform particle size, strong refractive index and high color reducing power, and has strong turbidity and Opacity, make the coating thin, smooth and strong acid resistance after enamelling. It can be evenly mixed with other materials in the enamel manufacturing process, does not agglomerate, and is easy to melt.
The ceramic industry is also an important application field of titanium dioxide. Ceramic grade titanium dioxide has high purity, uniform particle size, high refractive index, excellent high temperature resistance, and does not change ash at 1200°C for 1 hour. High opacity, thin coating, light weight, widely used in ceramics, construction, decoration and other materials.
