Hot Runner Technology In Molding

An introduction

The Hot Runner Technology (HRT) is an advanced and applied technology. The technique is lucrative more in injection molding. Certain providers of hot runner system noida have contributed to a great deal in optimization of product quality.

The hot runner technology lends a great deal of efficiency by increasing production, utilizing raw material, being energy effective and cutting down on the cost of production. Read on to find out how the hot runner technology in injection mold has been beneficial to the pet perform manufacturers in India. Several design instances technology in injection mold has supported the suitability of hot runner system.

It is important to note that the technology is applicable to the injection molds alone and not to all kind of plastic molds. However, hot runner system is applicable for a few types of thermoplastics.

Advantages of HRT

- Materials cost effective— no need to regrind or reprocess.  Less costly material  cost
- Lowering down energy costs, short and cycle times as there is no need to wait for   runners to cool down
- The small size of machines and reduced shot volume into runners
- The runners need not to be separated from the parts, the processing is automated Gates are stationed at the best of the strategic position for optimized economical design
- No runners to remove or regrind, thus no secondary work is needed
- Lower injection pressures
- Less clamping pressure
- Reduced cooling time
- Shot size reduced
- Cleaner and well maintained molding process
- Consistently constant  heat within the cavity

Disadvantages of HRT

- Hot runner molds are more complex and expensive to build than cold runner molds
- Escalated initial start-up costs than for cold runner systems
- Jeopardize sensitivity of materials causing thermal damage
- Extended temperature control is required which leads to delay in mold processing
- Higher maintenance costs which is more susceptible to breakdowns and heating   element failure

Future Of Injection Moulding Is Metal Injection Moulding

In the previous decade, both large and small injection moulding companies have witnessed shifting sands in the global business environment. Changes that tweak the moulding business environment are cost pressure from clients and relentless efforts to improve the productivity. Presently, more and more companies invest in cutting-edge tooling, automotive equipment and moulding machinery to gain competitive edge. Companies are hailing innovative, fresh assembly solutions at the moulding phase.

One such innovative moulding method is Metal Injection Moulding (MIM) that was introduced in the ‘70s. The beginning of MIM was a trifle shaky as the technology underwent several years of de-bugging. However, while ushering the 21st century, several moulding experts used the technology for overcoming their economic woes. 

Reasons that point MIM to be the future
  •     The technique has a market of $ 1 billion per annum
  •     The Compound Annual Growth Rate (CAGR) of the technique is slated to be 20 percent
  •     Such an exceptional growth of the technology is due to its cost-saving nature
  •     MIM cuts down the wastage of raw materials, which is common in conventional moulding
  •     The cycle time of MIM is reduced by 50 percent from that found in conventional moulding
MIM has become the primary growth factor for many technical players, belonging to firearm and medical sectors.  Also, the technology is accepted by Pet Preform Manufacturers in India churning out pet bottle moulds.

Which all sectors cherish MIM technique?
  •  Several firearm manufacturers herald the technology for manufacturing high volumes of sophisticated  weaponry. The technology saves oodles of resources that could be otherwise spent over high-priced gunsmithing and machining.
  •  Medical Equipment Original Equipment Manufacturers (OEMs) are utilizing the wonders of MIM   technique owing to its capacity to minimize cost.

The socioeconomic and microeconomic benefits of MIM make it an ideal solution to offer more value to clients.

What is Scientific Injection Molding?

There has been an upsurge in the demand of dimensionally stable as well as accurate parts and components in the medical sector. Several medical component manufacturers have examined the developments in injection molding and are keen to incorporate the technique for quick production of dimensionally precise medical equipment. Whether it is tight tolerance or thin wall, each of the demanding characteristics of medical components can be catered by a type of injection molding known as Scientific Injection Molding (SIM).

The SIM is an attempt to make the most of the current injection molding procedure. The Scientific injection molding can work with the conventional materials such as thermoplastic materials and other unconventional substance such as silicone rubber, thermoset plastics, high consistency rubber, and the like.

Why scientific injection molding is not a fixed process?

The process of SIM is variable. It depends upon the nature of the manufactured medical device. A little tribal knowledge and past practices help in further tweaking the existing molding procedure. The fine-tuning of the existing injection molding continues until the desired specification of a product has been met. However, building a robust SIM is a time-consuming procedure and requires process engineers to take into consideration several factors such as:-
  • PET preform mold design/construction
  • Part design
  • Process parameters (mold temperature, injection speed, melting temperature, hold pressure, cooling time, etc.) 
  • The molding machinery at work
  • The nature (including viscosity) of the material to be used

How SIM and lean manufacturing are related?

For many industrial players – especially the ones believing in lean manufacturing – scientific injection molding has become a culture. Lean manufacturing and SIM are interrelated as both emphasize on eliminating waste (such as downtime, over processing, defective products, excess inventory, to mention a few) and, thus, reducing the overall cost.

SIM is a data-driven approach based on thorough scientific analysis of the prevailing molding process. Several PET preform manufacturers are developing high-quality single stage Mould that is apt to be used in a scientific injection molding.
