Plastic molding processing

 is an engineering technology, which involves various processes to convert plastics into plastic products, so there are three common plastic processes: extrusion, injection molding, and blow molding.1. Injection molding

 the principle is to add granular or powdery raw materials into the hopper of the injection machine, and the raw materials are heated and melted into a flowing state. Under the push of the screw or piston of the injection machine, they enter the mold through the nozzle and the pouring system of the mold cavity, hardened and shaped in the mold cavity. Factors affecting the quality of injection molding

: injection pressure, injection time, injection temperature.

2. Extrusion molding

Extrusion molding, also known as extrusion molding, is mainly suitable for the molding of thermoplastics, and is also suitable for the molding of some thermosetting and reinforced plastics with good fluidity. The molding process is to use the rotating screw to extrude the heated and melted thermoplastic material from the die head with the desired cross-sectional shape, then shape it by the shaper, and then pass it through the cooler to make it harden and solidify to become the desired cross-sectional shape product.

3.Blow molding

Blow molding

 is to clamp the molten thermoplastic raw material extruded from the extruder into the mold, and then blow air into the raw material. The molten raw material expands under the action of air pressure and fits to the wall of the mold cavity. The method of finally cooling and solidifying into the desired product shape. Blow molding can be divided into film blow molding and hollow blow molding.

Film blow molding is to extrude the molten plastic from the annular gap of the extruder die into a cylindrical thin tube, and at the same time blow compressed air into the inner cavity of the thin tube from the central hole of the die to inflate the thin tube to a diameter Larger tubular film.

Hollow blow molding is a secondary molding technology that uses gas pressure to inflate a rubber-like parison closed in a mold cavity into a hollow product. It is a method of producing hollow plastic products.

The development of science and technology promotes social changes, and the advancement of flash memory chip technology has triggered a surge in the solid-state drive (SSD) market. Its excellent performance and gradually reducing costs have made SSDs increasingly replace traditional mechanical hard drives (HDD) in the storage field. It also plays an increasingly important role in the embedded computing applications we are focusing on today.

Today, flash memory chips are also in a new transition, from 2D NAND to 3D NAND. By vertically stacking memory cells in multiple layers to achieve higher storage densities and faster read/write operations, this evolution is notable and quickly.

At first, SLC was considered the most advanced because of its durability and fast read and write speeds. Over the past decade in which MLC has dominated the industrial market for quite some time because it is cheaper, with larger capacity, and better meet the general market demand. Since 2018, 96-layer 3D (BiCS4) SSDs have become commonplace in the market. In 2020, NAND directly jumped from 96 layers to 128 layers, bringing greater application opportunities to the entire market.


Today we focus on discussing several key points in the selection of SSD for embedded computers

, mainly from the working environment, hard disk capacity, erasing and writing cycles and so on.


As we all know, different equipment has different application fields, and different application fields have different surrounding environments, such as operating temperature, and some work indoors, with a temperature range of 0~70°C, while working outdoors may require considering

the subzero or high temperature factors. According to the current market division, it can be divided into -20~75℃, -40~85℃ and more extreme range  -55~105℃.

In addition, factors such as air humidity , dust , oxidation, and vibration should also be considered.


Proper use of hard drives starts with looking at available capacity, however, inconsistent specifications make it a challenge.

SSD manufacturers may set the full flash capacity (that is, the actual flash capacity), while some manufacturers may only set part of the capacity and use the hidden remaining capacity as spare capacity, which we call over provisioning (OP). The OP approach uses the extra flash capacity to perform garbage collection to improve hard drive efficiency and extend SSD life.

For example, for an SSD with a capacity close to 256GB, manufacturer A specifies the full 256GB, while manufacturer B specifies 240GB, and manufacturer C specifies 200GB. The actual available capacity of the hard drive may be less than the stated capacity. A common reason is that a flash area is used for internal processing. Therefore, engineers should conduct tests under near-real field conditions to analyze SSD performance and life. Manufacturers usually classify hard drives as "industry" or "consumer". Compared with consumer-grade SSDs, industry-grade hard drives are often used in data centers or servers, which require larger flash capacity as a reserve to provide more stable performance over a longer period of time. Especially for storage arrays, engineers should ensure that their design maintains low latency during peak loads, so the choice of capacity is also important in practical applications.




When choosing an SSD, lifetime endurance and write performance endurance are important criterions, as the wrong choice can come with considerable costs. Endurance does not play a role when using an SSD as the boot medium, but is very important for application scenarios responsible for data logging tasks.

Information on SSD write performance can be found in DATASHEET, usually in terabytes written (TBW) or drive writes per day (DWPD) as units. For example, a TBW value of 100 means that 100 TB of data can be written to the SSD over the whole life. The DWPD value represents how often the same amount of data is written to the SSD each day, for three to five years, depending on the capacity of the SSD, until it reaches its service life.

Several factors affect an SSD's endurance rating, including how best engineers implement wear leveling (evenly distributing data writes across all blocks in the SSD), write amplification factor, and W/E NAND flash cycles.

But engineers don't just rely on data sheet specifications, engineers need to use the proper tools to assess the right capacity, performance, and operating temperature to determine the achievable lifespan of an SSD in an application. In the application cases, the engineer should test the SDD under conditions similar to the actual application, then the SMART value in the test tool can be read. For example, in an application that needs to write a lot of small data (<4KB), the lifetime will be shortened, in this case, it is better to pack the data first and then write it. Additionally, the structure of an SSD causes the firmware to move incoming data multiple times until it eventually finds a place in flash memory, a process called write amplification factor (WAF). The higher the WAF, the more wear and tear the flash memory cells are, and the lifespan declines rapidly. Once the WAF is determined, and the corresponding TBW capacity is obtained from the datasheet, engineers can calculate the approximate write performance of the SDD.



The power supply is part of the industrial embedded application. If there is a problem with the power supply, errors will inevitably occur during the data transmission process. To solve this problem, a complex error detection and correction (ECC) function is implemented at each data transmission point. ECC protects data transfers between the host system and NAND flash by providing potential errors with complete end-to-end data path protection. Engineers need to evaluate the stability of the power supply, while also considering the effects of a sudden failure of the power supply voltage. The internal structure of an SSD and its programming of incoming data can cause certain problems, possibly even data loss.

Thanks to the low power detector integrated in the SSD, there is good protection for emergency situations. If a voltage dip is encountered, the SSD controller will stop accepting any further commands and attempt to save the data currently being transferred between the controller, cache and flash. Some SSD manufacturers

 take the extra step of placing capacitors on the SSD board to maintain the internal voltage to safely write data currently in the DRAM cache.

One of the important aspects of beverage packing is bottle. It is necessary to pay attention to your bottling because it can make or mar your production, packaging and ultimately distribution. Plus, there is a need to adhere to policies and government regulations guiding bottling and packaging of bottled products.

Here are a few tips for you to guide your choice of bottle blow molding machine, either as a new comer to the business or as an already established beverage producer.


What is a Bottle Blow Molding Machine?

The bottle blow molding machine is a machine that blows bottles.  The process of blowing bottles turns plastic pellets into hollow containers of equipment. The most known types of machines are PET and PC blow molding machines.


After the emergence of the bottle blowing machine as a replacement for most hand blowing, adopted by most beverage firms, it is convenient and quick in producing a large number of bottles.


In more simple terms, bottle blowing refers to the process of making bottles to be able to contain substances in them.


A series of processes are involved in the bottle blow molding enterprise, but the bottle blow molding machine combines all of these in one, saving time and becoming very efficient in carrying out the task.


There are generally two broad categories of the bottle blow molding machine, depending on the degree of automation and computerization. These broad categories can be mostly found in beverage bottling companies. They are;

· The old semi – automatic bottle blowing machine and

· The modernized automatic bottle blow molding machine.


While both of them are very effective, the automatic blow bottle machine is more effective and consumes much less energy and time as its semi-automatic counterpart.

 Features of Automatic Bottle Blow Molding Machine

The automatic bottle blowing machine is preferred above the semi-automatic for a number of reasons some of which are listed below;

· Concurrent pre-heating and blow molding, saving time and increasing the rate of manufacture.

· Elimination of the intermediate process of pre- heating separately from the blow molding.

· Microcontroller controlled and elimination of redundancy.

· Operation requires only one worker as it is easy to operate, thereby saving cost of production.

· Presence of a self-locking safety device to ensure operational safety.

· The electrical installation is relatively good except under very high temperatures and frequency.

· Friction and creep resistance are at minimal levels.

The automatic bottle blow machine has received a wide range of acceptability because of its applicability in the production of PET containers used for the packaging of a variety of goods such as drinking water, oil, beverages, cosmetics, oils, carbonated drinks and so on.


So if you are into the production of the goods mentioned above, then you need the bottle blow molding machine as it will reduce your cost of production and increase output.

How Does the Bottle Blow Molding Machine Work?

The process of blowing bottles involves a chain of actions, which if carried out separately will waste time and reduce efficiency.


Such processes as; feeding, heating, transferring and, stretching. But with the bottle blow molding machine, you do not have to worry.

A breakdown of how the bottle blow molding machine works is given below;

· the heated plastic embryo is pot into the mold

· the mold it tightened using the mold locking cylinder

· the mold expands through the movement of the cylinder locked with high pressure for pre blowing.
