Now Plastic Manufacturing on the Rise in China

The world of plastic products manufacturing has come a long way since the 1860s — and rapidly growing companies like CN-MOULDING are proof. While John Wesley Hyatt may not have realized it when he first experimented with cellulose nitrate in the late 1800s, the substance he discovered has since become a major part of everyday life in the China.

Today’s plastics are one of the most used materials on a volume basis in China. industrial and commercial life,” says PlasticsIndustry.org. “(They are) broadly integrated into today’s lifestyle and make a major, irreplaceable contribution to virtually all product areas.”

The two main types of plastics are thermoplastics and thermosets, the first of which is used to create many of the most common industrial, consumer and commercial products on the market today. What turns the plastic into a useful product is a process called injection molding, a high-production process originally launched in the late 1940s by American inventor James Watson Hendry.

Here’s how injection molding works: manufacturers inject the thermoplastic into a mold where it can set and form into the size and shape desired. While the process is fairly simple in concept, it offers a wide range of advantages, like higher production rates, lowered labor costs and reduced waste. And today’s businesses are increasingly moving their injection molding back to the China, to companies like CN-MOULDING, to experience further benefits like lowered freight costs, faster turnaround times, easier face-to-face meetings and quicker access to inventory. Choosing to do plastic products manufacturing within the China. means freed-up resources, lower lag times, and more convenience when making product adjustments or changes.

CN-MOULDING plastic products manufacturing provides all kinds of benefits to world companies,” said Kenny Han, a vice president at CN-MOULDING. “It’s much simpler to communicate, make changes, view samples and so on — not to mention cheaper and more efficient in the process.”


This increasing push for onshoring shows that China plastic products manufacturing is booming — and there are other evidences in place, too. Injection molding and 3D printing is a hot trend in the plastics industry today, being used for everything from military equipment to medical devices. Network World says 3D printing is “the hottest new technology on the IT landscape,” offering further proof that China plastic manufacturing continues to grow.

Injection molding process

The injection molding process can be roughly divided into the following six stages


Clamping, glue, pressure maintaining and cooling, mould and products.

The above process again and again, can batch periodically to produce products. Thermosetting plastic and rubber molding including the same process, but a thermoplastic material barrel temperature is low, the injection pressure is higher, the mould is heated, finished material injection in the mold of the subject to curing or curing process, and then strike off membrane.
The trend of the current processing technology is developing towards the direction of the high and new technology, these technologies include: micro injection molding, high filling compound injection, water injection, mixed with a variety of special injection molding process, foam injection molding, mold technology, simulation technology, etc.

The temperature control


Injection molding equipment and mold
1nitrogen-treated barrel temperature, injection molding process, the need to control the temperature of the cylinder temperature, nozzle temperature and mould temperature, etc. The first two main influence plastic plasticizing temperature and flow, and then a temperature is mainly influence plastic flow and cooling. Each kind of plastic flow with different temperature, the same kind of plastic, due to different sources or brand, the flow temperature and decomposition temperature is little different, this is due to the different average molecular weight and molecular weight distribution, plastic in different type of injection machine of plasticizing process is also different, so choose the cylinder temperature is not the same.

2. The nozzle temperature, nozzle temperature is usually slightly lower than expected tube maximum temperature, this is to prevent the molten material in straight through the nozzle may be "salivate phenomenon". Nozzle temperature also cannot too low, otherwise will cause early setting of melting and the nozzle clogging, or due to early coagulation material into the cavity affect the performance of the products.

3Pictures of mold temperature, mold temperature inner performance and apparent impact on the quality of products. Mold temperature is determined by the size of the plastic, of crystalline products and structure, performance requirements, and other process conditions (melt temperature, injection speed and injection pressure, molding cycle, etc.).
Pressure control

In the process of injection molding pressure including plasticizing and injection pressure, and directly affects the quality of plasticizing and plastic products.

1plasticizing pressure: (back pressure) adopts screw injection machine, screw at the top of the molten material in the screw rotating back pressure is called the plasticizing, which is also called back pressure. The size of the pressure can be found on the overflow valve to adjust the hydraulic system. In injection, the size of the plasticizing pressure is depending upon the design of the screw, the product quality requirements, and the type of plastic and needs to change, if the situation and the screw rotation speed is constant, increase plasticizing pressure will strengthen shearing action, which will raise the temperature of the melt, but will reduce the plasticizing efficiency, increase the current and leakage flow, increase the driving power.

In addition, increase plasticizing pressure often can make the melt temperature uniformity, color mixing and discharge gas in the melt. general
Injection molding in the operation of the pressure curve, the plasticizing pressure shall be on the premise of guarantee the products quality is lower, the better, the specific values are vary with the varieties of the plastic, but usually rarely more than 20 kg/cm2.

2. Injection pressure: in the current production, almost all the injection pressure of injection machine are in piston or screw at the top of the plastic

On the pressure (by oil pressure conversion) shall prevail. Injection pressure in injection molding, the role of is, to overcome the flow resistance of plastic flowing from cylinder cavity, given the rate of molten material molding and compaction of molten material.

In Coal-Powered China, Electric Car Surge Fuels Fear of Worsening Smog

Automakers' latest projections for rapid growth of China's green car market have added to concerns of worsening smog as the uptake of electric vehicles powered by coal-fired grids races ahead of a switch to cleaner energy.
Volkswagen AG plans 15 new-energy models over 3-5 years, its China chief told a green car conference in Beijing on Saturday, predicting - like the government - that Chinese production of electric and plug-in hybrid vehicles would grow almost six times to 2 million annually by 2020.

At the same event, BYD Co Ltd's chairman told media that the Chinese automaker's electric vehicle sales would double in each of the next three years.
The government has been promoting electric vehicles to cut the smog that frequently envelops Chinese cities, helping sales quadruple last year and making China the biggest market, the finance minister said at the conference. Less than 1 percent of passenger cars are now new energy, but the pace of growth raises their potential to worsen smog.
A series of studies by Tsinghua University, whose alumni includes the incumbent president, showed electric vehicles charged in China produce two to five times as much particulate matter and chemicals that contribute to smog versus gas-engine cars. Hybrid vehicles fare little better.
"International experience shows that cleaning up the air doesn't need to rely on electric vehicles," said Los Angeles-based An Feng, director of the Innovation Center for Energy and Transportation. "Clean up the power plants."
China plans to convert the grid to renewable fuel or clean-coal technology as part of efforts to cut carbon emissions by 60 percent by 2020.
That will speed the green impact of electric vehicles, said environmental science professor Huo Hong at the elite Tsinghua university. But that goal will be "really difficult to achieve."
Tsinghua's studies call into question the wisdom of aggressively promoting vehicles which the university said could not be considered environmentally friendly for at least a decade in many areas of China unless grid reform accelerates.
China's industry, environment and science ministries, which devise most new energy vehicle policies, did not respond to requests for comment. BYD and Volkswagen declined to immediately comment.
POLICY MISMATCH
To promote new-energy vehicles, the government has offered various incentives in recent years including tax breaks, and set targets such as having 5 million new-energy vehicles on the road by 2020 - more than 8 times the current number.
Authorities in some cities particularly affected by smog have gone further. Beijing and Tianjin, for instance, have exempted new-energy vehicles from limits on the number of new cars granted license plates, and exempted them from driving restrictions that other cars face on certain days of the week.

This month, the industrial Hebei province decreed that all new residential complexes must have car-charging facilities.
In western Beijing, 62-year-old retired truck and taxi driver Zhang Zhijun bought a BYD Tang hybrid last month and plans to trade in his gas-engine Toyota Corolla for an electric car for short rides like taking his grandson to school.
"Right now smog is very heavy in China. This way, if everyone does their part, it will definitely cut down on pollution," Zhang said.
But Beijing, Tianjin and Hebei are all more than 90 percent reliant on coal for energy, Tsinghua's research showed.
Huo and academics point out that, at the very least, the proliferation of electric vehicles pushes more sources of pollution away from heavily populated urban centers.
Whatever the impact, Qin Lihong, president of startup electric automaker NextEV, said cleaning the grid would be the quickest route to clear skies.
"It's much easier for society to make hundreds of power plants better than change the hundreds of millions of cars in thousands of cities," he said.

Introduction & Scope

INTRODUCTION

OBJECTIVES
This study focuses on the use of plastics in electronic components. It considers the wide range of thermoplastics and thermosetting polymers (including polyurethanes) that are being used in electronic components found in industrial, automotive and consumer electronics. It reviews the most recent developments in these materials that respond to the changing needs of the markets, and it analyzes the current and likely future sizes of these markets, broken down by component and by polymer type.

SCOPE AND FORMAT
This study covers all electronic components where plastics are used to a significant extent. It concentrates on components produced by injection molding, compression molding and encapsulation. It does not cover wire and cable, films used in capacitors or recording media, or enclosures. The study also identifies major material suppliers and key processors. It reviews important new technologies, as well as changes in legislation and industry standards and norms that may have significant effects on markets for electronic components, and it looks at interpolymer competition.

REASONS FOR DOING THE STUDY
Overall, plastics consumption in electronic components had been growing at rates well above those of growth in gross domestic product for many years. Electronic products have invaded virtually all areas of our personal and business lives, and their levels of sophistication continue to increase. The amount of electronics in automobile control, driver assist and infotainment systems is rising rapidly. Cloud computing is carried out on a massive scale, and now the Internet of Everything is connecting devices as well as people. At the same time, the tendency of many personal electronics to become fashion items has reduced product life cycles, with each new product generation putting new demands – in performance and especially cost – on the materials that go into them. In addition, the increasing visibility of electronic devices, most notably in mobile devices (smartphones and tablets), has been a key driver in pushing electronics companies to use more "environment-friendly" technologies and materials in their products.
