Overview Of Metal Injection Moulding Process?

Metal injection moulding is similar to the plastic injection moulding manufacturing process. The only difference is the use of metal powders along with plastic materials. Injection moulding company uses metal and polymer as raw materials for this process. This is referred to as feedstock. The following are the types of metal used in the metal injection moulding process.

  • Stainless steel
  • Iron
  • Copper alloy
  • Nickel alloy
  • Cobalt alloy

Here are the detailed steps involved in the metal injection moulding process

Preparing feedstock: This is the first step in the metal injection moulding process. Here the polymer and metal mixture is prepared. The mixture is then granulated into a fine powder. The final feedstock contains 60% of metal powder and 40% polymer. The polymer acts as a binding agent.

Injection moulding cycle: This is the second step where the molten feedstock is fed into the mould cavity. It gets cooled and takes the shape of a mould. It is called the green part. The Injection moulding companies carry out metal injection moulding using machines used for the plastic injection moulding process. The mould cavities are made large to perform this cycle.

Debinding: This is the next step in metal injection moulding. Here the polymer is removed from the moulded metal. The solvent debinding and thermal debinding process help in removing the polymer present in the green part. The brown part is the outcome of the above process.

Sintering: This is the final step carried out in the metal injection moulding process. In this step, the brown part is placed in a high-temperature furnace. It removes the pores and shrinks the mould. The finished part is of high density and helps in creating high tolerant industrial components.

Important factors to look for in materials for dental tools

All dental care facilities want to give their patients the very best treatments done with care and precaution. If you own such a facility that takes care of every aspect, you will also take the utmost care to choose the type of dental instruments you utilise.

Well-made dental tools have certain qualities that make them worth the investment. Here’s what every dentist looks for when choosing their dental tools:

  • Completely non-corrosive, rust-free materials that will survive exposure to any environment.
  • Highly durable materials that exhibit good tensile strength and fatigue strength.
  • High resistance to wear and tear and good edge retention.
  • Easy to clean and maintain.
  • Environmentally-sustainable materials can be easily recycled when the old instruments are replaced with new ones.

Stainless Steel: Why it is the best for dental instruments

There are many reasons why Stainless-steels.in recommends stainless steel for your dental instruments. Leading dental care facilities like 4 Squares Dentistry prefer stainless steel for its amazing properties that we will discuss further along in this article.

Why do we recommend stainless steel for dental use?

The reason is very simple: Stainless steel has all the characteristics required to manufacture dental instruments. Also known as Inox, stainless steel is mostly preferred for its very high corrosion resistance. Another highlight is its price point, which is much less when compared to other materials.

The other big advantages of using instruments made of stainless steel are:

  • Durability

Stainless steel is synonymous with durability and strength. There’s no such thing as chipping, peeling, breaking, or damaged by heat and chemicals with stainless steel. This amazing quality is also one reason why stainless steel instruments can survive the demands of sterilisation. Despite its amazing fatigue strength and tensile strength, stainless steel is also very ductile, making it easy to design and manufacture instruments to your preference.

  • Resistance to wear and tear

Due to its incredible strength, stainless steel can retain its edge retention once a dull instrument is sharpened. This property is crucial for dentists because dull, worn-out instruments can cause harm to the patient during a dental process. Galling and wear resistance are other crucial properties to look out for to ensure the instruments are sharp and precise.

  • Easy maintenance

Some of the latest stainless steel dental instruments in the market are coated with micelles to make them extra bacteria-resistant. Stainless steel can also be easily cleaned with sanitising solutions.

  • Corrosion resistance

One of the most attractive stainless steel properties is its resistance to corrosion in any environment, made possible by the thin oxide layer on the steel’s surface. The ratio of chromium in the steel also plays an important role in making it corrosion resistant. However, the only downside is that it can discolour or corrode when exposed to bleaching agents or tartaric acid.

Types of stainless steel favourable for dental instruments

Click Here – Manufacturers use either Austenitic stainless steel or Martensitic stainless steel to make surgical instruments. When it comes to dental instruments, there is a whole range of stainless steel with different grades. The most commonly used grades are listed below:

  • Type 301: Known for its high resistance, flexibility and strength.
  • Type 302: Preferred for its easy fabrication and maintenance and is lightweight.
  • Type 304: serves to manufacture a large range of instruments as it is resistant to dyes and organic or inorganic chemicals.
  • Type 305: Known for its high strength-to-weight ratio and its attractive finish.
  • Type 308: Better than 305, it is preferred for its high ductility, oxidation and heat resistance and is extremely weldable.
  • Type 405 & 409: Both grades have great corrosion and oxidation resistance and are used to manufacture tools meant to last for days.
  • Types 420, 430, 440: All three grades are great choices for manufacturing dental tools and instruments that exhibit properties of heat resistance, oxidation resistance, ductility, thermal conductivity, and an attractive finish.

High-grade stainless steel is very apt for manufacturing quality dental tools such as probes, dental mirrors, dental pliers, dental explorers, intraoral photography mirrors, diagnostic kits, etc. Stainless steel makes your dental instruments worth the investment and improves the quality of your dental care.

What you should know about stainless steel?

Posted on

The usage of stainless steel has become so prominent these days. Most of the devices and tools that we use in our day to day life are made of stainless steel only. In this scenario, it is really good to know something about stainless steel.

Stainless steel is not a naturally formed metal. It is an alloy that is made combination of two metals – iron and chromium. When iron is added with at least 10.5% chromium, the chromium produces oxide layer on the steel surface that is highly resistant to corrosion. By increasing the amount of chromium, the steel becomes more resistance to the corrosion. Additionally, the steel also contain carbon, manganese and silicone. Sometimes, elements like Molybdenum and nickel are also added to steel for superior formability and corrosion resistance. Most people say that stainless steel is corrosion-free, which is not true. Though stainless steel does not corrode or rust like steel, it can get stained in when exposed to rare conditions. There are different grades of stainless steel made for use in different areas and environment. The stainless steel was discovered in the year 1913 by Sheffield, who was well known metallurgist that time. He found the stainless steel while he was experimenting different types of steel for making weapons. He found that iron with 13% chromium didn’t get rusted after many months. Today, stainless steel is used in applications that demand strength and increased corrosion. To know more about the uses and applications of stainless steel, you can browse the internet.
