Defects In The Preforming Process Of Pet Preform

When it comes to Pet Preform molds, defects that are not easily observed usually lead to the biggest problem. For example, excessive loss of intrinsic viscosity (IV) is known to complicate the reheat stretch blow molding process, reduce stress crack resistance, and cause other bottle quality problems. Historically, molders have not easily „seen“ IV, but things are different now. Manufacturers should never find themselves inadvertently carrying unqualified preforms on top of the game. The location of the bottle.

The measured intrinsic viscosity of PET is related to the molecular weight. It is known that bottles having a high molecular weight or intrinsic viscosity have better physical properties and barrier properties than bottles having a low or intrinsic viscosity. This makes high IV resins ideal for packaging pressurized beverages such as carbonated soft drinks. The resins specified for these applications typically have an initial IV in the range of 0.83 – 0.86 dL / g. Some IV losses should be expected during melt processing, while for carbonated soft drinks, the minimum acceptable value for minimum bottle IV is 0.80 dL / g.

Excessive IV loss during injection molding is often attributed to improper drying or melt processing conditions. However, it may also come from low molecular weight materials such as recycled materials, recycled PET, colorants and other additives. The obtained preform IV can also be reduced by simply receiving a defective raw material resin. Regardless of the source of the IV excess loss, it is easy to ignore it without the proper tools and training. However, this is not the case.

With the right training and equipment, your injection molding technician and quality team can predict preform IV in real time in each machine cycle. The minimum requirement to achieve this capability is usually one day of machine time, followed by analytical testing. After the data is compiled, it can be used to set limits to trigger an alarm on the molding machine or to provide meaningful limits for the statistical process control system. Alternatively, the predicted preform IV can be reported directly using the system upgrade machine. If you want to get products with few defects, it is a good choice to choose a China Pet Bottle manufacturer.

Open Type Rotary Screen Printing Machine Control System Requirements

The Open Type Rotary Screen Printing Machine is a method of printing using a seamless cylindrical screen. It began in the 1960s and developed rapidly, becoming a new printing method for fabrics. The rotary screen printing machine is characterized by the continuous rotation of the rotary screen for printing, which not only maintains the style of screen printing, but also improves the printing production efficiency.

In the control system of the rotary screen printing machine, the two main problems are solved. The first one is the synchronization between the feeding frame, the printing guide belt, the drying room conveyor belt and the falling frame, and the synchronization between them ensures the fabric. When passing through the four units continuously, they are neither stretched or even broken, nor wound. This kind of synchronization is given by the main motor as the other three way. The tension frame is used to realize the automatic adjustment of the closed loop speed, so as to achieve the synchronization between the four, usually by the simulation of „synchronous controller“ or PLC. The output module is used to implement this synchronization.

The second synchronization is the synchronization between the rotation of the rotary screen printing machine (that from the professional Hot Air Stenter manufacturer – Licheng) and the movement of the conduction belt, which is one of the most critical technologies in the printing machine. The synchronization accuracy of the two determines the printing precision of the whole printing machine, how to improve the circle The synchronization between the net and the conduction band and the synchronization accuracy between the nets have become one of the most important problems in the system design. Compared with the independent transmission of the rotary screen, the traditional mechanical coaxial transmission has obvious gaps. The main differences are as follows:

1. There are many transmission links, and the accumulated error is large, which affects the printing precision.

2. With the mechanical wear, it is easy to appear „running flowers“, affecting the stability of the printing quality.

3. Variety adaptability is limited and it is not suitable for processing heavy structures.

4. The longitudinal versus flower range is limited.

There are different types of Fruit Juice Production Line machines on the market today. But the basic work and components behind these machines are almost identical. The highest intent behind the invention of the fruit processing line is to maintain the sensory properties of the fruit, such as its aroma and color at an optimal level. The best way to preserve fruit is heat treatment. This will confer microbial stability and the temperature must be assessed to avoid protein degradation of the fruit. The heat treatment process of the fruit depends on the pH of the fruit. The pH of an acid such as citric acid, malic acid or tartaric acid is between 1,5 and 4,5. Heat treatment is a careful combination of temperature range and time period.

For heat treatment, the possibility of fruit oxidation is very high if air is present. In order to avoid the risk of the oxidation process, the entire process is carried out under vacuum conditions. For this purpose, a vacuum evaporator is in use.

The evaporation process removes all water and other solvents from the fruit. The evaporation process helps to concentrate the pulp. The pulp can be concentrated by two methods, but depending on the nature of the pulp, a suitable method can be employed. Forced circulation vacuum evaporator for fruit puree and pulp juice. To this end, the centrifugal circulation pump forces the pulp through the plate heat exchanger. For clarified juices, multi-effect vacuum evaporators are also known as falling film vacuum evaporators.

Do you want to choose a reliable vacuum evaporator? Don’t miss Shanghai Jimei Food Machinery Co., Ltd., we are experts in this field, and we also provide professional Milk Processing Plant, welcome dairy products to contact us.

When purchasing a filling machine, Juice Processing Plant must purchase filling machines suitable for their own business development. People want to make the purchase of the filling machine to achieve its own value as much as possible, then what requirements should the company meet to customize its own filling machine?
a, mechanical design. The main working mechanism of the filling machine consists of storage tank, filling main machine and variable frequency speed control transmission door. The mechanical body is divided into two parts, one of which is the design. The quality of product quality, whether it can make customer satisfaction depends first on the product design and development process, and the design and development of the product is the prerequisite for product upgrading and product quality. The design directly determines the formulation of the production plan, the procurement of raw materials, the difficulty of process production, the type of equipment and processing accuracy, the level of quality, etc., poor design may make the product difficult to produce.
b. On-site installation. During the installation process, if the parts are not properly installed in the part, or there is a certain deviation, the accuracy, supply and efficiency of the machine may be caused during the operation of the machine. It directly affects the stability of the machine during operation and the offset of the labeling position.
c, the installation environment. The environment is a major factor affecting quality. According to the space and environment produced by the enterprise, such as air temperature, the site, such as the label is lower than the humidity, then the label is not attached to the bottle; or because the humidity of the bottle is not within the tolerance range, during the filling process, A similar situation occurs. If the installation environment is windy, it will have a very small impact on the product, but with a slight improvement, the problem is easy to solve.
If you want to buy a filling machine, Shanghai Jimei Food Machinery Co., Ltd. is a good choice for you. We are experts in this field. Or do you needMilk Powder Making Machine equipment? We are also a manufacturer worthy of your choice.
