4 Tips you should know when start an Injection Molding Quote

 Any new project must be started with a senior purchasing manager to review the injection molding quotation. The whole process of injection molding quotation is complex. You need to take time to collect information and investigate the authenticity. Here we explore this work in 4 aspects.

Good graphics, and good design is a work guarantee

Each customer can provide different information. This depends on the extensive experience of the purchaser. If the goal is to achieve the most accurate quotation. A complete 3D drawing, including each part allocation relationship, is the basic requirement. Some meticulous companies will provide prototype samples, which is perfect. If the customer does not have 3D design capabilities, find some industrial designers to help. And we mold engineers can give you advice on how to optimize the original design. The goal is to reduce development costs without compromising product performance.

Precision and quantity

If you want an accurate quote, the most important point is the number of parts and the accuracy you need.

Keywords:

Required quantity: each ordered quantity, the planned supply life.

Accuracy requirements: The part may be in trial operation or in a long-term manufacturing operation. Coordination relationship between individual components, key dimension requirements for individual parts.

Injection molding quotes need to be as detailed as possible for offer preparation.

These factors are important not only for manufacturing but also for design. Mold design may vary depending on your order quantity requirements, such as using stronger tool materials to increase life and using multi-cavity mold design to increase production.

Analysis and understanding

Needless that each part is different, and it is doomed to be different. Even similar parts, because the intended use is not similar, the injection molding quotation will be different.

Providing clear information is also important for injection molding quotes. We continue to emphasize that injection molding service providers should be as far as possible.

Understand the actual project. Knowing that you want to sell expectations or market applications, injection molds can better help with material selection or even part design. The best injection molding machines, the best operating technicians, will also be able to help you achieve the professional industry and use.

Any certification or other regulatory requirements.

Application in specific examples:

High temperature resistant and low-temperature resistant products

Large automotive plastic products

Medical use-grade products

Food-grade products

Injection molding quotes will tell you what design matters and what your product needs.

Characteristics of Injection Moulding

 Characteristics of Injection Moulding

Injection molding is a method of plastic production. At a certain temperature, stir the fully melted plastic mother particles with screws, and inject the melt plastic particles into the mold cavity, after cooling and curing, to get the injection plastic parts.

Injection process

The whole process is divided into six stages: mold clamping, injection molding, pressure protection, cooling, mold opening, and removal of plastic parts. These six stages directly determine the quality of injection molding products, and these six stages are a complete continuous process. Injection molding is an important plastic molding method suitable for the mass production of plastic parts with complex shapes and precise size requirements. With the application of injection plastic products, the quality of plastic parts is also improving.

Parameters Setting

During injection molding, the process parameters will directly affect the flow state of the melt and the quality of the final plastic parts. Acquisition and maintenance of optimized process parameters are a prerequisite for forming high-quality plastic parts. Injection molding is a widely used molding method.

Why are Hollywood blockbusters that have become less and less popular in China in recent years?

 Fast & Furious 9 Release 17 Days With Only 1.3 billion-CNMOULDING Tell You Real Chinese Market

Not "more and less popular", but "no good migrant films in recent years"

(Little knowledge: migrant workers film means that even migrant workers are watching, describing its high heat)

Hollywood dipped with superhero movies. When the limelight is booming, they call British fans lemon essence and are prophet when the type declines. Of course, there is also the impact of the delay of shooting progress. Good films will generally not be selected, but only bad films will try their best to overcome the difficulties and go public in time.

Apollo 13 Fast and Furious ugly, right? However, before Independence Day 2 Global Storm was already ugly. But at that time, many of the good films reached the heat of migrant workers, until the good films did not, only garbage.

I didn't catch up with the wave of dance and western movies, but the 1990 s wave of science fiction and action movies I caught up with —— Now you think 5% of it was good, but 95% of the audience didn't escape.

There are actually good movies right now, such as 1917. But this kind of high-quality film often has limited commercial popularity. If you really want to drive the market, —— for something like Iron Man 1 and Nolan Batman is either new or meaningful.

For example, due to the popularity of GoldenEye 007, the action film + was a hit in the 1990 s, and Mission: Impossible was the beneficiary. The old IP movies absorb the elements of the tough guys of the 1980 s action movies and refresh the CG technology of the science fiction movies. But within a few years, the audience was tired of watching, Bruce South after the post-007 reputation is very subtle, "Mission: Impossible 2" is also controversial, then "Impossible" came out, everyone exclaimed, "action films can be done like this!" So we see Putin 007 style 180 degrees of change.

As for whether the taste of Chinese film audiences will be dominated by Chinese films in the future, I am very definitely impossible.

The truth is very simple when the Japanese economy is booming, it is the world's largest film market outside the United States. However, the top of the Japanese film box office is a lot of imported films, domestic films rely on animation to support the scenes. Hollywood movies are not American blockbusters, Hollywood movies are commercial blockbusters, as long as the market is commercial, it must not fight Hollywood.

As for the domestic film market, it is hard to say, because foreign films can be banned in China as if domestic TV stations ban Japanese animation. However, after the ban, domestic animation turned over the decision? No, we all ran to the Internet to watch the Japanese animation. Now the Internet also began to ban Japanese animation, so the domestic animation will turn over? Impossible.

What are the different types of molds?

   

 I. Mold classification:

Classification by hardness: soft mold and hard mold (quenching treatment). 

Classification by Grade Quality: Grade 1 Grade 3 by difficulty: Grade A B Class C Class D by mold size: super large medium small

II. Definition of mold hard die and soft mold:

1, mold hardness: soft mold, hard mode 1) Soft mold: mold steel has been pre-hard, no quenching treatment, but the hardness is low, HB below 400, the production life is less than 500,000 times, widely used.

2) hardened mold: the mold steel is annealed, divided into two rough machinings and finishing. After rough processing, the hardness is above HRC48 °. Keep the processing allowance of about 0.2. After rough processing, the tooling will have deformation to prevent the finishing can not meet the requirements. Production life is over 50 ~ 1 million times, with the most applications of small molds.

III. Mold quality grade: Grade I, Grade III, Grade I mold quality

1, mold: must be capable of one million or more opening times. This is the primary mold, the customer requires to make the best mold with the best materials and accessories.

 2. The requirements of Grade I mold are as follows:

(1) Detailed mold design (connecting the computer drawings and materials);

(2) Most mold embryo hardness

To have an HB280;

(3) The core shall be hardened by all HRC50, positions, and accessories;

(4) Medicare side division pipe jacking pin;

(5) line position must have wear-resistant pieces;

(6) temperature control monitor shall be installed in mold, brother, or position;

(7) It is recommended to make all the cooling water channels with nickel plating (ELECTROLESS NICKEL PLATING) intended to prevent rust and easy cleaning;

(8) The positioning lock shall be added to the mold line.

Analysis of Plastic Mould Industry in 2021 in China

 Current Situation, dilemma, prospect, and trend

       As an industrial supporting facility, its development level is affected by the development of automobiles, electronics, aerospace, military industry, medical care, and other building industries. Data show that in 2019, the sales revenue of enterprises above the designated size of China's plastic injection mold industry reached 272. 7 billion yuan. The China Business Industry Research Institute predicted that the sales revenue of enterprises above the designated size of China's injection mold industry will reach 281. 6 billion yuan in 2020. 

I. Development status of the mold industry

In recent years, the mold industry through technology introduction, digestion and absorption, and re-innovation, the professional production capacity of mold enterprises has been greatly enhanced, the modern mold industry system has been basically formed, and the industry has achieved leap-forward development. The manufacturing technology of mold products has reached or is close to the international level, the quality is more reliable, and the international competitiveness has been significantly enhanced. China mold occupies an increasingly more important position in the international procurement pattern. Data show that in 2019, China's mold export amount reached USD 6. 246 billion, and in 2019 it was USD 1. 939 billion, down 9.37%. 

Among all the mold types, the plastic and rubber mold is the largest mold import and export variety in China. Data show that in 2019, China's plastic and rubber molds export amount reached USD 3. 967 billion, accounting for more than 60% of the total import and export of molds in the same period, reflecting the strong competitiveness of China's automobile molds and home appliance mold products in the world. The import amount of plastic rubber molds is the US $ 870 million, accounting for more than 44.89% of the total import amount of molds, indicating that there is still a large import replacement space for plastic rubber molds in China. 

II. Development dilemma of the mold industry

1、Shorshortage of professionals

The mold talent training cycle is long, and the lack of industry technical management talents, especially high-end talents, restricts the development of the industry to a certain extent. Generally speaking, training an excellent mold engineer requires several years of professional training and practical experience accumulation. China's mold industry started late, and there is a relatively short of professional skilled talents and management talents, which can not well meet the market demand and limit the rapid development of the industry. 

2、 product standard lag affects the industry development

China's national standards and industrial standards system of mold products need to be improved, the international influence is insufficient, and the formulation and revision of some product standards lag behind to a certain extent, which is not conducive to the sustainable and healthy development of the industry. Due to the lack of product standards or outdated standards, the role of the standard system in standardizing the market, promoting technological progress and product development is limited, and it has failed to guide enterprises to produce complete kinds and excellent quality products, leading to disorderly competition, leading to overcapacity in middle and low - end molds, and high - end molds still need to be imported. 

Low degree of the professional division.

3、Low degree of specialization

The mold production process is complex, long production cycle, mold enterprises tend in order to pursue scale, adopt wide coverage development strategy, from process design to research and development, from processing to assembly test mold, although integrated production helps to improve the control of the product, but reduce the level of division of labor and cooperation, and the loss of production efficiency is not conducive to the improvement of technology and product quality. Focusing on inter-bank competition and the lack of horizontal cooperation mode will cause repeated investment, and eventually lead to China's large but weak mold industry and the lack of international competitiveness. 

Which plastic material is as transparent and beautiful as the glass?

 The CNMOULDING recommendation must be a PMMA

Organic Glass (Polymethyl methacrylate) is a popular name, abbreviated to the PMMA. The chemical name of this polymer transparent material is polymethyl methacrylate, which is a polymer compound formed by the polymerization of methyl methacrylate. It is an important thermoplastic. Plexiglass is divided into colorless transparent, colored transparent, bead light, pressed flower plexiglass. Perpoxiglass is commonly known as acrylic, medium publicity pressure acrylic, acrylic, plexiglass has good transparency, chemical stability, mechanical performance and weather resistance, easy to dye, easy processing, beautiful appearance, and other advantages. Plexiglass is also called gelatin glass, acrylic, etc. 

Organic glazing is widely used, 

Not only in the business, light industry, construction, chemical industry, and so on. And Plexiglass production, in advertising decoration, sand table models are widely used, such as signs, billboards, lightbox panels, and Sino - English letter panels. 

Material selection depends on the modeling design, what kind of modeling, with what kind of organic glass, color, variety should be tested repeatedly, so that it to achieve the best effect. With a good modeling design, but also rely on careful processing, in order to become a beautiful handicraft. 

1. building application: window, sound-proof doors, and windows, lighting cover, telephone booth, etc

2. Advertising application: lightbox, signboard, signs, display frame, etc

3. traffic application: doors, windows of trains, cars, and other vehicles

4. medical application: baby care box, various surgical medical appliances, civilian supplies: sanitary ware facilities, crafts, cosmetics, stents, aquariums, etc. 

5. Industrial application: instrument surface plate and protective cover, etc. 

6. Lighting Application: fluorescent lamp, chandelier, street hood, etc

7. home application: fruit plate, paper towel box, acrylic art painting, and other household daily products

Machinery

Plexiglass has the above excellent performance, making it extremely widely used. In addition to being used on aircraft as a cockpit cover, windscreen window, it is also used as the windshield and windows of the Jeep, sunroof (anti-breakage), screens for television and radar, shields for instruments and equipment, the housing of telecommunications instruments, telescopes and optical lenses on the camera. 

There are many kinds of daily necessities made of organic glass, such as buttons made of bead light organic glass, all kinds of toys, lamps are also because of the decorative effect of stained organic glass, and appear particularly beautiful. 

Medical care

Plexiglass also has a wonderful medical use, that is to make artificial corneas. If the transparent cornea of the human eye is covered with opaque substances, the light can not enter the eye. This is the blindness caused by a total corneal leak and the disease cannot be treated with medication. 

Therefore, medical scientists imagine using the artificial cornea instead of the cornea covered with white spots. The so-called artificial cornea is to use a transparent material into a mirrored column with a diameter of only a few millimeters and then drill a small hole in the corner of the human eye, the mirror column fixed on the cornea, the light through the mirror column into the eye, the human eye can again see the light. 

As early as 1771, ophthalmologists implanted their corneas with optical glass, but not successfully. Later, using crystal instead of optical glass, also became ineffective for only half a year. In World War II, some aircraft were wrecked when cockpit covers made of plexiglass were blown up and fragments of it were embedded in the pilot's eyes. After many years, although the fragments were not removed, there were no further causes of human eye inflammation or other adverse reactions. This accidental event indicates good compatibility between Plexiglass and human tissue. At the same time, it also inspires ophthalmologists who can use organic glass to make an artificial cornea. It has good light transmittance, stable chemical properties, non - toxic to the human body, easy to process into the desired shape, and can be compatible with the human eye for a long time. Artificial corneas made from plexiglass have been commonly used in clinical practice.
