At present on the market, the injection molding process can realize the mass production of a piece of goods, more suitable for batch processing of a certain part, for standardized production, such as the production of toys, aviation, aerospace, electronics, machinery and other fields. As a new emerging technology, 3d printing can make 3d printing materials into required models through digital computer technology, which can effectively shorten the processing time. It is widely used in children's education makers, architectural design and even medical industry

3d printing technology began to enter people's life in the late 1980s. And injection molding technology is the traditional industry to use more than one processing technology, often used in 3d printing technology comparison, which is the weight of the two. We explain the difference between 3d printing and injection molding from five aspects: principle, processing quality, cost, production model and application field.

The automotive industry has become a major application area for MIM components such as engines, gearboxes, turbochargers, locking mechanisms, steering systems and electronic systems.

The surface treatment of steel parts generally has two types: alkaline oxidation method and acid oxidation method. Acid oxidation is also known as "blue".

D2 is a tool steel with a carbon content of 1.5%, a chromium content of 11.5%, and a heat treatment hardness of up to 60HRC. It is a kind of semi-stainless steel. D2 steel has good wear resistance and moderate toughness. The disadvantage is that the corrosion resistance is slightly insufficient. It is a kind of steel suitable for practical use. Bob Dozier likes to use D-2.

For parts with large machining allowance, in order to make them have better heat dissipation conditions during processing, and avoid heat concentration, symmetrical machining should be used during processing.

Forging is a processing method that uses a forging machine to apply pressure to a metal blank to cause plastic deformation to obtain a forging having certain mechanical properties, a certain shape and size.

The traditional metal padlocks which is commonly used on many families have many shortcomings on padlocks. One of them is if house-owner forgot to take the keys, then they have to ask the locksmith to open or break their lock by themselves. Moreover, the metal padlocks have a low security because they can be easily unlocked by people who familiar with mechanics. As the traditional lock raised a security issue, more and more locks company realized that it is necessary to provide safer door lock such as smart lock which use facial and fingerprint recognition to provide a much convenient and safe way to lock the door.

The 440C steel is a martensitic stainless steel. The carbon content is 1.0% and the chromium content is 16-18%. Strong rust resistance, high quality stainless steel.

There are two types of sintered carbon steel and alloy steel. Sintered steel is produced by powder metallurgy. A material or product obtained by press molding and sintering steel powder.

It is understood that Samsung and Intel giant IT is also stepping up its pace to study wearable devices, such as Samsung recently released the bending battery can be used for wearable devices. Intel set up the "China intelligent equipment innovation fund", It is not hard to see from the IT giants acting that they had high hopes for Chinese wearable device market.
