What Happened When Mould Making Met System Engineering?

By many, system engineering and mould making are referred to as two sides of the same coin. The discipline of applied science lets students invent new items and techniques for doing a particular job. Likewise, invention is the heart and soul of mouldmaking. Hence, there has to be some connection between mouldmaking and system engineering. Read on to explore...

An example to explain the close affair between systemized engineering and mouldmaking

At present, the market for trim panels that are used in a car’s interior is large.  Use of a high-quality injection mould is done to manufacture the best-in-class automotive trim panels. The plasticised trim panels for a car’s interior have to be both stylish and functional. Surfaces of interior automotive trim panels have to be appealing as finished panels become the Unique Selling Point (USP) for most cars.

 In addition, devotion as well as attention is given to a car’s instrument panel, dashboard, headliner, inner door panels, etc.  The trim panels have to be relentlessly redesigned to introduce freshness in a car’s interior. The mouldmaking for trim panels is complex, speedy and innovative.  Many trim panel mouldmakers bank upon the concepts of the discipline for being:-

•    Innovative
•    Fast paced
•    Able to carry out complex detailing

Mould designers who are and aren’t in support of system engineering

Most mouldmakers believe that system engineering must be left to the Original Equipment Manufacturers (OEMs). Those mouldmakers who don’t want to tweak their working process never endorse system engineering.

Nevertheless, a few forward-thinking mouldmakers opine that a small, significant portion of system engineering will play a pivotal role in the overall business. The discipline helps in making the overall process of mouldmaking highly innovative. Further, every contemporary mould designer believes that the engineering principles help in expounding the scope of moulding. Also, mould designers require the discipline’s principles to manufacture injection-moulded parts in no time.

Let’s clear the air between systemized integration and engineering

Mixing the principles of system integration and engineering helps improve communication, thus, resulting in excellent mould manufacturing.  Let’s clear the difference of the meanings of the two terms.

•    Systemized integration

System integration helps in connecting actual/physical assets of a company. The process joins the entire factory floor system – machining, testing, assembly as well as packaging – that’s used in manufacturing. System integration is defined as the physical counterpart of systemized engineering.

•    Systemized engineering

The discipline is multifaceted. Mouldmakers use the engineering discipline to determine a client’s requirements in the very beginning (while designing development cycle) of the process.  Systemized technology helps mould designers understand requirements (technical as well as business) of a client.

The joining of systemized engineering along with integration is strategic. Blending the two approaches helps mouldmakers design high-quality injection moulds for ASB Machines and other specialized equipment.

Joining both the concepts with mouldmaking proves to lessen the complexity of the process. A moulding process’ complexity rises whenever technological shifts take place. Combining the principles of engineering and integration helps mouldmakers grapple with such dramatic technological shifts.

Everything About Plastic Injection Molding



Most products used on an everyday basis never get a thought from a layperson about their making. As a rule, nearly every article is made using plastics, glass, metals and rubbers. However different the material of production may be, the process remains the same – injection molding. Among all such materials of construction, the most common one is plastic.

The evolution of plastic injection molding industry  

At present, close to thirty million tons plastic are manufactured on a day-to-day basis. The significance of plastic as a material for construction is due to its high availability; almost 60,000 variants of this material are manufactured at present.

However, the prosperity of injection molding technique began with the innovation of resins such as Styrene, K Resin and Nylon 6/6. Another factor that propelled the growth of this molding technique was the manufacturing of ultraviolet inhibitors and different additive colors. 

In 1980s, the plastic material was given prominence with the development of horizontal injection molding machinery. With the beginning of high-end vertical mold machines and hybrids molding systems, it became possible to manufacture plastic products with unimaginable contours and tight dimensional tolerances. In the past, the process of molding was daunting and accounted for several injuries. However, the development of technology (such as robotic controls and hydraulics) has helped the process become safer with each passing day.

How plastic molding industry got better?

Notwithstanding the wonders of plastic injection molding, the procedure drew flak from several green revolutionists due to the material it used. However, large shares of revenue and energy are spent to make plastic environmentally more acceptable.

With the fruitful attempts to make plastic recycling possible, the entire process of injection molding has become efficient. The developments of high-strength thermosetting polymers have helped enhance the durability by leaps and bounds. Several pet bottle moulds are made from thermosetting polymers to increase their strength and capacity to withstand high temperature.

Apart from injection molding, one of the most common techniques used for manufacturing hollowed plastic products is blow moulding. Presently, innovative plastics are introduced to make possible impeccable precision and close-tolerances in the final product.

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.

Plastic Bottle Manufacturing Through Blow Molding Techniques



Nowadays, the consumers’ convenience is placed at the highest priority by players belonging to several industries, especially the plastic bottling sector. The plastic bottle manufacturers are leaving no stone unturned to give consumers bottles that are aesthetically pleasing and easy to handle.

In earlier days, the plastic bottle producers had a tough time in shaping the bottles, especially those having complex contours. Even after hard work and dedication, the results were not satisfactory. Such growing frustration urged several plastic bottle producers to take help of technology. After research, a technology finally came up that assisted plastic bottle manufacturers in reducing their everyday manufacturing distresses; the technology came to be known as blow molding.

What is blow molding all about?

The most trusted process for creating plastic containers and hollowed components is blow molding. In blow molding, the plastic is shaped by several processes such as stretching the material, injection or extrusion.  The process gets started by heating and consequently melting the PVC, polythene, or any other plastics before beginning the molding process. The melted plastic has to be transferred to hollowed tubes. Compressed air is used in the hallowed tubes for giving the molten plastic the desired shape.

The blow molding process at a glance

Beginning the blow molding process is no rocket science. The process begins by feeding the plastic granules to the storage compartment. The storage container has motorized threads meant to rotate as well as compartmentalize granules. The compartments (having granules) are subject to extreme heat. Once the granules are melted, they are transferred to the mold. The mold is subjected to intense air pressure, helping the molten plastic to acquire the desired shape.
