There are all kinds of products on the market. In addition to distinguishing from the barcode, what other factors can we distinguish? Of course the most important thing is the label of the product. So why do products have to be labeled? What exactly do labels do?
The reason for labeling
The barcode of a product represents each product, while the label represents a kind of product. First of all, labeling a product not only allows customers to have a general understanding of the product in appearance, but also can quickly get information such as product usage from the label text. A good label can also make customers have a deep memory of a certain product.
Secondly, the product label carries important information such as manufacturer information and product ingredients, so it is obviously so important to label the product.
What are the functions of labels?
1. Labeling identifies the product
Label helps to identify the product and brand. It popularizes the product and its brand name.
2. Labeling grades the product
Label helps to express grade of the product. For example, wheat can be express with the grades such as 1, 2, 3, 4. Label becomes useful to grade any product according to its quality.
3. Labeling describes the product
Label gives introduction of the product, describes and expresses its grade. Information and instructions about- who manufactured the product, when and where it was manufactured, how many ingredients have been used in it, how to use the product, how to keep the product safe, etc. are given on the label. This becomes helpful to the customers.
4. Labeling promotes the product
Label helps to promote the product. Customers’ attention is drawn by attractive and fascinating graphs, figures or marks. This motivates the customers to buy the product. Label plays and important role in sales and distribution as it makes the customers take buying decision.
5. Labeling protects the customers
Label protects the customers. As maximum selling price, quantity, quality etc. are mentioned on the label, the customers are protected from the possible malpractice of middlemen.

Injection mold is a tool for producing plastic products. To meet the needs of molding parts, we need to pay attention to some matters when choosing injection molds and put forward corresponding requirements.
1. High corrosion resistance Many resins and additives have a corrosive effect on the surface of the cavity. This corrosion causes the metal on the surface of the cavity to corrode, peel off, deteriorate the surface condition, and deteriorate the quality of the plastic parts. Therefore, it is best to use corrosion-resistant steel or chrome-plated or cymbal-nickel treatment on the surface of the cavity.
2. Good wear resistance The gloss and precision of the surface of injection molded parts are directly related to the wear resistance of the surface of the injection mold cavity, especially when glass fibers, inorganic fillers, and certain pigments are added to some plastics, they Together with the plastic melt, it flows at a high speed in the runner and the mold cavity, and the friction on the surface of the cavity is very large. If the material is not wear-resistant, it will soon wear out and damage the quality of the plastic parts.
3. Good dimensional stability During injection molding, the temperature of the injection mold cavity should reach above 300 ℃. For this reason, it is best to choose tool steel (heat-treated steel) that has been properly tempered. Otherwise, it will cause changes in the microstructure of the material, resulting in changes in the size of the injection mold.
4. Easy to process Most of the mold parts are made of metal materials, and some structural shapes are very complex. To shorten the production cycle and improve efficiency, the mold materials are required to be easy to process into the shape and precision required by the drawings.
5. Good polishing performance Injection plastic parts usually require a good gloss and surface state, so the roughness of the cavity surface is required to be very small. In this way, the surface of the cavity must be surface processed, such as polishing, grinding, etc. Therefore, the selected steel should not contain rough impurities and pores.
6. Less affected by heat treatment To improve the hardness and wear resistance, the injection mold is generally subjected to heat treatment, but this treatment should make the size change very small. Therefore, it is best to use pre-hardened steel that can be machined.

Injection Molds Classification or types of mold injection very depend on what we need to make the plastic parts， because every part has a specific and unique design. when designing molds we must see the influencing factors, like geometry, number of cavities, ejection principle, plastic material and shape of parts. Below we will explain the mold classification with a few most seen types of injection molding molds.
(1) Single parting surface injection mold
When the mold is opened, the movable mold and the fixed mold are separated to take out the plastic parts, which is called a single parting surface mold, also known as a double-plate mold. It is the simplest and most basic form of injection mold. It can be designed as a single cavity injection mold or a multi-cavity injection mold according to needs. It is the most widely used injection mold.
(2) Double parting surface injection mold
The double parting surface injection mold has two parting surfaces. Compared with the single parting surface injection mold, the double parting surface injection mold adds a partially movable intermediate plate (also called the movable gate plate, There are gates, runners and other parts and components required for the fixed mold), so it is also called a three-plate (moving template, intermediate plate, fixed template) injection mold;
It is often used for single-cavity or multi-cavity injection molds with point gate feeding. When the mold is opened, the intermediate plate is separated from the fixed platen by a certain distance on the guide column of the fixed mold, so that it can be taken out between the two plates. Pouring system condensate. The double-parting surface injection mold has a complex structure, high manufacturing cost, and difficult parts processing. It is generally not used for the molding of large or extra-large plastic products.
(3) Injection mold with side parting and core pulling mechanism
When the plastic part has side holes or undercuts, it is necessary to use a core or slider that can move laterally. After injection molding, the movable mold first moves down a certain distance, and then the inclined section of the curved pin fixed on the fixed plate forces the slider to move outward, and at the same time, the push rod of the demoulding mechanism pushes the push plate to make the plastic part form itself. Take off the core.
(4) Injection mold with movable molding parts
Due to some special structures of plastic parts, the injection mold is required to be equipped with movable molding parts, such as movable punches, movable concave molds, movable inserts, and movable threaded cores or rings, etc., which can be combined with the plastic parts during demolding. They are removed from the mold together and then separated from the plastic part.
(5) Automatic unthreading injection mold
For threaded plastic parts, when automatic demolding is required, a rotatable threaded core or ring can be set on the mold, and the mold opening action or the rotation mechanism of the injection molding machine, or a special transmission device can be used to drive the thread. The core or threaded ring rotates, thereby dislodging the part.
(6) No runner injection mold
The runners injection mold refers to the method of adiabatic heating of the runner to keep the plastic between the nozzle and the cavity of the injection molding machine in a molten state, so that there is no gating system congealing when the mold is opened and the plastic parts are taken out. The former is called adiabatic runner injection mold, and the latter is called hot runner injection mold.
(7) Right-angle injection mold
Right-angle injection molds are only suitable for angle injection molding machines. Different from other injection molds, the feeding direction of this type of mold is perpendicular to the opening and closing direction during molding. Its main flow channel is opened on both sides of the moving and fixed mold parting surfaces, and its cross-sectional area is usually unchanged, which is different from other injection molding machine molds. The end of the main flow channel is used to prevent the injection molding machine. The wear and deformation of the nozzle and the inlet end of the main flow channel can be replaced by a replaceable flow channel insert.
(8) Injection mold with ejection mechanism on the fixed mold
In most injection molds, the demolding device is installed on the side of the movable mold, which is conducive to the work of the ejector device in the mold opening and closing system of the injection molding machine. In actual production, because some plastic parts are limited by the shape, it is better to leave the plastic parts on the side of the fixed mold for molding. To make the plastic parts come out of the mold, it is necessary to set the mold release on the side of the fixed mold. mechanism.

It is dangerous to make mistakes when installing a shrink wrapping machine. So be sure to pay attention when installing a shrink wrapping machine. Heat shrink packaging machine is one of the more advanced packaging methods in the current market. It uses shrink film to wrap the product or package outside. After heating, the shrink film wraps the product or package tightly, fully displaying the appearance of the item, improving the product’s displayability, and increasing the aesthetics and sense of value. At the same time, the packaged items can be sealed, moisture-proof, anti-pollution, and protect the goods from external shocks. The role of heat shrink packaging machines is very important, and it has become indispensable shrink machine equipment in society.
1. The heat shrink packaging machine and the winding machine consume a lot of power, so the power of the input power must be greater than the nominal power on the nameplate of the shrink machine, otherwise it is easy to burn the lines or electrical components.
2. Like the baler, the machine must be grounded reliably to protect personal safety.
3. Each machine is shipped with a cable for connecting to the power supply, and the lead part of the terminal has the identification symbol of the power supply, which must be connected correctly. The illegal operation may lead to electric shock.
4. When the specified voltage of the machine is a three-phase 380V power supply, the zero line must be input at the same time, that is, the standard three-phase four-wire system other packaging equipment is also like a vacuum packaging machine. Otherwise, the machine can not work normally, and it is easy to burn the internal electrical components.
5. The machine must be installed horizontally, otherwise, the service life of the electric heating tube will be shortened. For machines that are conveyed by mesh belts, the inclined installation will cause the conveyor belt to be off-center.
6. When the machine is used continuously for more than three months, the temperature-resistant wires in the shrinking chamber should be checked and replaced as appropriate according to their aging degree.
7. When the machine is working, the operator’s palm and other parts are not allowed to contact the operating parts of the machine, especially the temperature inside the shrink chamber is extremely high, which is easy to burn.
8. After the packaging work is completed, the heating switch should be turned off first, and the conveying motor and the fan motor should continue to run for about 10 minutes, and then the entire power supply should be cut off.

If we are in the logistics transportation packaging industry, or we specialize in the import and export packaging of goods, there are many factors that we must consider when choosing the type of material for the equipment we are transporting, because we want all the goods to arrive safely at their destination.
For transport packaging safety reasons, it would be beneficial to know more about industrial shrink packaging and the benefits it provides.
What is Industrial Shrink Film Packaging?
The main feature of heat shrinkable film packaging is that it is a flame retardant material, which means it is heat resistant and fire-resistant. Therefore, it is used in the freight and warehousing sector to protect equipment products.
This material is made of polyethylene and thermally bonded rubber, obtained by sealing PET plastic with a heat gun.
We have to keep in mind that when we pack goods, we have to use flexible and durable materials, and shrink wrap plastic is perfect for this.
Industrial shrink wrap is a very flexible and at the same time very durable material.
Due to its particularity, it can be used for any type of equipment packaging, whether angled or irregular, as its shrink wrapping capability allows adaptation to all types of product packaging protection.
Shrink wrap is ideal and offers great benefits for our shipments.
