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.

CNMOULDING's technical mold has developed a manufacturing process for manufacturing small-scale, high precision molds that assures our automotive, medical, and home appliance customers that they are investing in accurate, consistent, repeatable shooting molds.

High precision molds are the leader in designing and manufacturing molding systems by original equipment manufacturers who need to optimize production, reduce production costs, and maintain their position as China's premier mold manufacturer.

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.
