Commonly Used Materials for Metal Injection Molding (MIM)
https://www.jlymim.com/commonly-used-materials-for-metal-injection-molding-mim.html
1. Introduction of Metal Injection Molding
Metal injection molding (MIM) is a near-net-shape process suitable for small, three-dimensional complex shape products with special performance requirements. This technology is a new near-net-shape technology in powder metallurgy, which is formed by introducing modern plastic injection molding technology into the field of powder metallurgy.
MIM process flow is as follows: all kinds of fine metal powder (generally less than 20 μ m) and the preset binder, mixed with a certain proportion, are made to the feedstock with rheological properties. By injecting the feedstock into the mold cavity through an injection machine, the semifinished products are formed. After removing the binder and sintering at a high temperature, various metal parts can be obtained.
2. What is the Ideal Mim Powder Like?
The particle size, tap density and particle shape of MIM powder are the key performance indicators to determine whether the powder can be successfully used in the MIM process. MIM process requires very fine powder (~10μm) to ensure uniform dispersion, good rheological properties and a high sintering rate.
The ideal MIM powder has the features as follows: the powder size is 2-8μm; the bulk density is 40 %~50 %; The tap density is more than 50%; the powder particles are nearly spherical with a large specific surface area.
At present, MIM metal powder raw materials include iron, nickel, titanium, stainless steel, precious metals, superalloys and other materials. At the same time, it is developing towards diversification, such as structural materials, functional materials, magnetic materials and so on.
The main production methods of MIM powder are carbonyl method, ultra-high pressure water atomization method, high pressure gas atomization method, plasma atomization method and laminar flow atomization method. Different powder preparation technologies have different effects on the grain size of powders, particle shape, microstructure, chemical properties, manufacturing cost and so on.
3. How to Choose a Binder for Metal Injection Molding?
Binder is the core technology of metal injection molding. Compared with the conventional powder metallurgy method, MIM has a significant difference of high binder content. The main function of the binder is to act as a carrier for the flow of bonded metal powder particles and to maintain the shape of the workpiece after molding.
The binder for MIM shall meet the following requirements:
Small contact angle with powder, strong adhesion and no reaction with powder;
The viscosity changes little in the range of injection temperature, but the viscosity changes fast in cooling, so it is difficult to stick the mold;
A relatively small amount of binder can make the mixture have better rheological properties.

SELL BUSINESS OUTCOMES INSTEAD OF JUST PRODUCTS
In Future most chemical companies will move from B2B push models to business-to-business-to-consumer (B2B2C) models. Digital technology and concepts such as Industry 4.0 will be leveraged to deliver sustainable, co-developed applications, services, and business outcomes. Companies that have identified an experience gap will gain a competitive advantage by engaging more closely with their customers and ecosystem partners. This engagement will enable them to deliver outcome-driven services and address customer expectations. This experience, along with developing customer relationships based on trust and shared values and risks, will be the new paradigm.
They will establish searchable intellectual-property databases to access relevant scientific information to create co-innovated products and solutions. Having established this foundation, they will extend into properties prediction and performance of new formulations to significantly shorten the development process and time to market while monitoring product and formulation compliance along the entire lifecycle. Furthermore, they will extend into their customers’ value chain, monitor process parameters, and allow in site quality control in real-time through sensors at customer operations. The implementation of Industry 4.0, where all sensors, devices, machines, and other equipment are connected in one single network, will provide an unprecedented amount of insight that eventually reveals new business opportunities, such as predictive maintenance, further improving the product experience. In terms of logistics, they will track and trace material flow and product integrity along the entire value chain.
Finally, they will collaborate on open innovation platforms, turn data into value-based services, and establish transformative business outcome-driven and customer-centric revenue models to improve quality and reduce costs and risks for customers.
OUTCOME-BASED CO-INNOVATION IN CHEMICAL COMPANIES
Traditionally, chemical companies have developed products in response to market needs driven by downstream industry sectors, such as consumer products, pharmaceuticals, engineering, and construction. In the future, chemical companies will strive for unprecedented levels of customer experience by anticipating market trends and needs, rapidly developing and manufacturing corresponding formulations and selling based on business outcomes, such as first-pass-quality semifinished parts or goods, instead of selling by quantity. Innovative technologies, such as machine learning, the IoT, artificial intelligence, and blockchain, enable these processes. A cumbersome, multistep development process and a traditional revenue model based on product quantity delay time to market and time to value.
Solutions offered in New World Scenario: Chemical Company simulates property and performance of new formulation using machine learning.
Top Value Drivers

Summary
With growing competition, ongoing globalization, and blurring industry boundaries, companies can no longer afford to focus solely within their own four walls. Established business models and practices based on linear value chains are no longer sustainable in an era where companies are expected to be responsible for the emissions of their suppliers, customers, and other downstream business partners.
To survive and thrive in today's competitive environment, companies cannot rely solely on organic growth. Instead, more and more are turning to mergers, acquisitions, and divestitures to expedite portfolio adjustments and diversify into promising new markets or segments. The business model is being challenged by the mass commoditization of products and formulations, global competition, higher demand from consumers for sustainable products and operations, and exponentially increasing regulatory requirements. In conclusion, those who are willing to evolve will be welcomed by the market, while those who are not willing will be lost in the crowd.

How To Scrub The Plastic Extrusion Machine In China
The china plastic extrusion machine extrusion machine produces pellets, which are the uncooked materials for plastic polymers.
What is a plastic extruder?
A plastic extruder is a machine that's used to supply varied varieties of plastic products. It's composed of a quantity of different components, including a barrel, which is where the plastic pellets are melted and turned into merchandise; a feeder, which provides the pellets to the barrel; and a die, which shapes the plastic pellets into the desired form.
How does the plastic extruder work?
The plastic extruder is a machine that melts the thermoplastic pellets after which extrudes it by a die to create semifinished products. The extrusion course of happens in two phases: the feeder and the die. In the feeder, the pellets are fed into the die, the place they're melted and then pressured by a small opening at high speed. This produces the finished product, which is then ejected from the die and collected on the opposite side of the machine.
Advantages of Using a Plastic Extrusion Machine

If you're desirous about learning more about plastic extrusion machines, or if you're already utilizing one and want to learn extra about how to keep it clean, we suggest studying our weblog put up.
Disadvantages of Using a Plastic Extrusion Machine
The plastic extrusion machine is an effective way to produce high-high quality plastic products. However, there are some disadvantages of utilizing a plastic extrusion machine that should be considered earlier than making the purchase. The first drawback is that plastic extrusion machines are very noisy. This can be a problem if the machine is utilized in an industrial setting the place sound levels are vital. Additionally, the noise can be disruptive to employees who are attempting to work on other duties. Another drawback of using a plastic extrusion machine is that the plastic produced by the machine is commonly brittle. Because of this it's troublesome to create products that are sturdy and durable. As well as, the plastic produced by a plastic extrusion machine usually has a “plastic smell” which will be unpleasant.
What's inside and out of doors of the machine?
The plastic extrusion machine is one in all the most important machines in a plastics manufacturing facility. It can be used to provide quite a lot of merchandise equivalent to bottle caps, medical tubing, and bumper caps. The machine consists of two important parts: the extruder and the die. The extruder is a large metallic body that sits on a rotating platform. The die is a small metallic field that sits on high of the extruder and melts the plastic pellets into tubes. The extruder has several openings that permit air and plastic pellets to circulate into and out of it. The plastic pellets are heated by the recent air flowing by way of the extruder, and this heat causes them to melt. The melted pellets are then pressured by means of the openings in the die, which shapes them into tubes. The extruder and die have to be clear to ensure that the plastic tubing produced by the machine is of top of the range. There are several methods to wash the extruder and die: guide cleansing, utilizing automated cleaning machines, or utilizing a mix of each strategies. Manual cleaning includes cleaning the inside and outdoors of the machine with brushes or different objects. Automatic cleansing machines use brushes, jets, or other objects to clean the machine.
