parts as well as small parts, in today’s high competition of the market, most the companies are looking for Plastic Mold China company to support their business.

Plastic injection moulding is one of the most common techniques used by various manufacturers. This technique is getting very popular since its ability to be used in mass-production as well as for prototypes of products. Plastic injection moulding is a very technical process in a general way.

Plastic injection moulding can be utilized for making plastic products having open-ended and solid shape. A screw-type plunger is utilized in the process for getting the preferred shape of the molten plastic material. This technique is basically a flexible, fast and customer-driven operation performed to get efficient plastic products. This technique also can help you in getting fast turnaround products in large quantities as well as in small quantities.

The key process in plastic injection moulding is when the melted plastic is forced into a plastic mould, the part of the machine that receives the plastic and shapes it accordingly. In ST’s terms, the basic idea in this process is inserting molten liquid plastic into a mould, and when allowed to cool, the mould is removed to reveal the object. As soon as the plastic cools to a solid state, the finished plastic is ejected from the press and mould.

The process of plastic injection moulding can also be thought of in its most simplistic terms. The three phases that are used in this process are heating which is melting plastic usually pellets which soften, shaping which is where force contains it, and cooling that enables it to retain its shape. Injection moulding machines involve a high degree of pressure, which help keep the mould closed during the injection process.

If one considers such a business, it is important to research all areas before beginning. One should consider the design process, where an industrial designer or engineer first renders the design. When it is made into a mould, a metal container houses the manufactured products, and eventually onto store shelves. Plastic injection moulding could produce plastic moulding products which are ubiquitous. Most commonly used for plastic tubes, toys, bottles, accessories, bottle caps, car parts, grips, and kitchen utensils, etc.

During plastic injection moulding process, you can utilize the latest 3D Solid Modelling CAD systems to create a conceptual design, manufacture production plastic mold china, mould the plastic parts on one of many injection moulding machines and finally, you may finish the product in our assembly and packaging department.

Plastic injection moulding uses thermoplastic materials such as plastics that soften and fluidize when heated. The plastics used in the injection molding process are liquefied at temperatures between 220° C and 270° C. After liquefaction, the molten plastic is pushed into a closed die, where it hardens into the shape configured by the die cavity.

Plastic injection mold press is simple called press. Plastic injection mold press holds the plastic mold china in which the components are shaped. Mold press is rated by tonnage, which expresses the amount of clamping force that the machine can generate. This pressure keeps the mold closed during the injection process. Tonnage can vary from less than 5 tons and big than 5000 tons, with the higher figures used in comparatively few manufacturing operations.

Plastic injection mold press can fasten the plastic molds in either a horizontal or vertical position. The majority is horizontally oriented, but vertical machines are used in some niche applications such as insert molding (go to https://www.plasticmold.net/plastic-mold-china// to know more about insert molding) allowing the machine to take advantage of gravity.

Plastic injection mold press is used to create many things such as milk cartons, packaging, bottle caps, automotive dashboards, pocket combs, and most other plastic products available today. It is known that injection molding is the most common method of part manufacturing. It is ideal for producing high volumes of the same object. Go to https://www.plasticmold.net/plastic-mold-china/ to know more about injection moulding.

Some advantages of using Plastic injection mold press is high production rates, repeatable high tolerances, the ability to use a wide range of materials, low labour cost, minimal scrap losses, and little need to finish parts after molding. The materials you can use in injection molding are chosen based on the strength and function required for the final part. However, each material has different parameters for molding that must be considered.

If you are a plastic parts manufacturing company that produces anything from toys to car parts and you are not using Plastic injection mold press to produce your parts, you will spend too much money.  Indeed, using Plastic injection mold press provides additional savings to manufacturers because plastic is less expensive than metal and manufacturers pay for fewer parts. As a result, they are widely used because of the high quality of the end product.

One of Plastic injection mold press you can choose in the market is Plastic Injection Molder (YS-1180). This machine has moving platen featuring box type bridge structure and full-connected rear high-rigidity mold platen. Through finite element analysis, it can prevent deforming of mold platen, resist against fatigue, have high repetition accuracy, distribute mold closing force uniformly, greatly increase mold’s service life and reduce injection molding cost.

Another option of Plastic injection mold press is HDT-200 200ton plastic injection molder. This machine comes in two series; HDT series and HDF series. The HDT machines’ clamping force is from 80 tons to 2200 tons and the shot weight is from 80g to 2kg. These machines have strong locking force and a very good injection precise also a stable performance etc.

Meanwhile, the HDF machines are a type of high-speed Plastic injection mold press. The machine’s cycle time is very short (2.6 seconds-3.6 seconds) with a high injection pressure (to be possible to reach 240MPA) and a high-speed injection (to be possible to reach 600MM/S). This machine can be used to produce the thin-wall products, especially the thin-wall snack boxes and containers (with the wall thickness of 0.4mm).

The injection techniques of poly terephthalic acid alcohol ester (PET)

The chemical name of PET is poly terephthalic acid alcohol ester, also called polyester. At present, GF-PET is used by most clients. PET Injection Mold China parts are mostly used in the bottle preform products

PET has a good rheological property in molten condition and pressure has more effects on viscosity than temperature does. Therefore, we change the rheological property mainly from the pressure.

Plastic drying

Due to PET macromolecule contains an aliphatic base, it has certain hydrophilicity. The aggregate is very sensitive to water when it’s at a high temperature. When the water content exceeds the limit, the molecular weight of the PET will drop during the processing, so the product will be colored and become crisp. Therefore, we need to dry the material at 150 Celsius degree for more than 4 hours and 3 to 4 hours at 170 Celsius degree before processing. We can use air injection method to examine whether the material is completely dry or not. The proportion of recycled material is generally not more than 25%, and the recycled material needs to be completely dried.

Selection of injection molding machine

PET can only be stable for a short time after the melting point, and the melting point is so high, which needs to choose the injection system which has more temperature-control periods and less friction heat when plasticizing, and the product’s (the material which contains water) actual weight cannot be less than two-thirds of the amount of machine injection.

Mold and gate design

We generally use hot runner mold to design PET bottle preform. It is better to have an insulation board between mold and Injection Mold China machine template. Insulation board’s thickness is about 12 mm, and can bear high pressure. There is enough exhausting effect for it so as not to appear local overheating or chipping, but the vent’s depth is generally not more than 0.03 mm, otherwise, it is easy to produce flashing.

Plasticizing temperature

It can be measured by the air injection method. The temperature is ranging from 270 Celsius degree to 295 Celsius degree and the enhanced GF – PET’s temperature can be set from 290 Celsius degree to 315 Celsius degree, etc.

Injection speed

Generally, injection speed must be fast, in order to prevent premature solidification. But if injecting too fast, the shear rate would be so high that the material would become fragile easily. The material injection is usually completed in 4 seconds.

Packing

In order to avoid wearing, the packing pressure shall be as low as possible. Generally, it’s not more than 100 bar. We usually don’t need to use it.

Detention time

It should avoid overlong detention time to prevent from the molecular weight declining. Try to avoid the temperature above 300 Celsius degree. If the machine stops less than 15 minutes, we only need to make air injection; If the machine stops more than 15 minutes, we should not start the machine again until we use viscosity PE to clean the machine and make the feed cylinder’s temperature drop to PE temperature.

Attentions

(1) Recycled material cannot be too much. Otherwise, it’s easy to form “bridging” at discharging chute which will influence the plasticizing.

(2) If we don’t control the mold temperature or the metal temperature properly, it’s easy to produce “white fog” and become opaque. When the mold temperature is low and even, the cooling speed shall be too fast with few crystallization and transparent products.

First, we would like to share you some basic knowledge of plastic injection molding

Thermoplastic plastic injection molding method that is molten plastics material and then injected into its membrane cavity( we call plastic mold). Once the molten plastic into the mold, according to it by cold-like cavity molding into a certain shape. The shape is usually the final product, or as in the installation of the final product is no longer required before the use of other processing. Many of the details, such as the Department of uplift, rib, screw, can step in the injection molding operation out.

injection molding machine has two basic components: for melting and plastic injection into the mold and die equipment installations. Die devices and the role is:

• 1. The mold injection withstands the pressures of closure;
• 2. Products will be removed in the plastic injection devices inject die before their melting and then control the speed and pressure injection mold to melt.

The current injection devices have two design: Screw pre-plasticizing or a two-stage device and reciprocating screw. Screw pre-plasticizing for the use of pre-plasticizing screw (first level) then injected into molten plastic-injection materials (second level).
Screw pre-plasticizing of molten advantage is the quality of constant, high pressure and high-speed, and precision of the injection volume control (using both ends of the piston stroke thrust mechanical device). These strengths are transparent, thin-walled products and high production rate required. Its weaknesses include the uneven length of stay (leading to material degradation), high cost of equipment and maintenance costs.

Chinese plastic molds are significantly cheaper than molds from other countries especially, molds from western companies. In order to save money, many countries are indeed trooping to China to take advantage of this price variation. Despite this affordability, it is important for companies to take several steps in order to ensure that they do not fall prey to the numerous low-quality mold makers in the country. First and foremost, companies should carry comprehensive research on the available mold makers in China. Before making the final purchasing decision, companies should inspect the quality of the molds made by different mold shops and ensure that their purchasing decision is informed by this inspection.

In addition to inspecting the quality of the molds, companies should scrutinize the terms and conditions of the plastic mold makers. This should enable the company to enter a contract with the most the mould makers who offer the most suitable terms. For instance, one of the most important considerations to make when it comes to the terms of sale is the nature and period of the warranty. Companies should select mould companies that offer the most suitable period and warranty terms.

Injection Molding |plasticmold.net

most plastic solid materials are produced? It is called Injection molding china. It is a simple process. However, the process may require practice for efficiency. What is the process of Injection molding? During the process of plastic injection molding china, the plastic is heated till it melts and is introduced, under pressure (injected), into a mold. The mold may be made up of any metal such as steel or aluminum. The molten form is then allowed to cool down and set into a solid form.

The plastic material thus formed is then retrieved out of the plastic mold. The actual process of plastic molding is just an expansion of this basic mechanism. The plastic is let into a barrel or chamber under gravity or force-fed. As it moves down, the increasing temperature melts the plastic. Then, the molten plastic is forcibly injected into the mold under the barrel with an appropriate shape. As the plastic cools, it solidifies. The injection molded parts like this has a reverse shape than that of the mold. A variety of shapes both 2D and 3D, can be produced by the process.

The process of plastic molding is cheap due to the simplicity involved and the quality of the plastic material is modifiable by changing the factors involved in the custom injection molding process: – The pressure of injection can be changed to change the hardness of the final product. – The thickness of the mold also governs the quality of the article produced. – The temperature for melting and cooling determine the quality of the plastic formed. ADVANTAGES The major advantage of injection molding is that it is very cost effective and fast. Apart from this, unlike the cutting processes, this process rules out any undesired sharp edges. Also, this process produces smooth and finished products that require no further finishing. Go to our other page to more knowledge on injection molding china,
