Technology Advancing Injection Molding Companies Through the Industry

Every industry can be massively improved with the right technological advancements. Even in larger corporations, having one or several systems that work seamlessly to provide a service or product will see benefits. There are more and more ways to cut down on costs without sacrificing quality in the injection mold process.

Thin Wall Molding – This kind of molding achieves the same plastic part with a thinner wall. The process is more or less the same; however, no aspect can be left unchecked from the part and mold design to the result ensuring the product will not lose any quality with the thin wall molding. The geometry must be done just so to achieve the outcome desired without any cracks or damages.

3D Printing – This kind of technology is critical in developing a prototype for injection molding. With a prototype already constructed before the entire process begins, there’s a convenient timeframe allowing for any potential improvements to be made before starting the final product. It takes the process one step further as opposed to standard online rendering.

Liquid Silicone – One of the most critical components of plastic molding is thermoset. Cold material is injected in with a scorching hot mold to create one final part. However, there may be times where you’ll need to produce a piece that can withstand extremely high temperatures or chemicals. At this point, consider the advantage of thermoplastic molding, which usually includes liquid silicone.

Gas-Assisted Injection Molding – Thicker products run the risk of distortion as it cools down, however, with gas-assistance, the injection molding is constantly shooting gas into the mold to help maintain a smooth finish on the exterior. The interior should remain at the same quality, all the while keeping expenses at a minimum.

What Can We Expect in the Future for Injection Molding

As the year comes to an end, you may be thinking about what’s going to change in the new year. With many businesses searching for ways to be innovative in how they manufacture and sell their products, looking at advancements that increase production time yet decrease overall cost seems to reign king.

Scientific Molding

The smallest variations within molding design can have the most significant effects on the final product. Keeping a precise process and not deviating from it will have the result be pristine each time. Scientific molding offers a higher level of precision than traditional molding may not be able to produce. The specifications or requirements may not be within a range that traditional molding is capable of maintaining.

Scientific molding monitors each step throughout the procedure including temperature, viscosity, and moisture content. Maintaining constant high-quality is the main focus of utilizing scientific molding. The scientific molding process is meticulous and heavily monitored throughout each step to avoid any variations that can cause the product to be rejected.


For products that require an extra layer on the outside, that’s where over-molding comes into play. For tools, specifically, the ones that need a grip handle on the outside can now benefit from over-molding using two or more materials at the same time to achieve the same result. Production costs severely decrease with allowing a single product to be manufactured in one fell swoop.

Conformal Cooling

Although still useful, traditional mold methods are equipped with straight-line cooling channels. With conformal cooling, the lines adapt to the shape of the product, thus reducing the overall cycle time. Conformal cooling offers more uniformity helping to make the part stronger, reducing the number of rejected products being made in various industries.

Top 5 Most Common Plastics Used for Molding

The process of selecting the right plastic can be an extensive process because there are so many different types that are durable, and useful in several industries. Quality is one component we absolutely will not compromise on because that’s what we run our business on. Plastics have variations that are applicable in automotive, medical, and food and beverage businesses.

Most Often Used Resins

  1. ABS – Acrylonitrile Butadiene Styrene (ABS) is used often because it’s sturdy, durable, and showcases incredible impact and temperature resistance. ABS can be used for any standard thermoplastic processing methods because it readily adheres to other materials. The disadvantage is that ABS doesn’t offer any chemical resistance, making it useless for products that require electrical insulation or UV resistance.
  2. injection molding thermoplastic machine close upAcetal – This type of thermoplastic provides toughness, chemical solvent resistance, easy colorization, and minimal moisture absorption. Ideally, it is used within the food and beverage, mechanical, and automotive industries. It is most beneficial with products that physically touch because the friction is insignificant.
  3. Polypropylene – This plastic is heavily known for its chemical resistance, elasticity, toughness, and insulation properties. PP already offers a wide range of applications, but because it can be easily modified and altered, the possibilities are endless. PP is flammable and susceptible to UV radiation but still offers effective resistance.
  4. HIPS – High-Impact Polystyrene (HIPS) is extraordinarily cost-efficient yet offers excellent impact resistance, customizable surfaces, and is aesthetically pleasing. HIPS is mainly used in print applications because it is specially made for graphic arts. However, it can also be applied in appliances, TV and AV equipment, and computer coverings.
  5. LDPE – Low-density polyethylene (LDPE) provides excellent water resistance, incredible strength, and chemical endurance. It is used to a wide range of everyday products and applications like houseware, consumer goods, and medical and agricultural products. With recycling the plastic product, LDPE lives on in various alternative products like floor tile, furniture, and trash cans. LDPE is problematic to bond and isn’t useful in harsh weather or high temperatures.

Injection molding is a very intricate, complex process. There are numerous components to consider from the plastic resin all the way to the correct shape of molding to create the perfect product make the entire process elaborate but rewarding to see the finished outcome. Plastic injection molding requires little to no handy work after the initial production; allowing everything to run as smoothly as possible.

The Basics

Essentially, plastic injection molding is a simple process. The machine follows a step-by-step process to achieve the ultimate goal. Pellets of plastic are loaded into the device, then transported into a mold while being heated to molten along the way. From that point, the plastic cools within a short period and then taken out of the frame to receive its newest shape.

The Advantages

First and foremost, the possibilities are endless with the proper injection molding process. Because the procedure has been tweaked and perfected over many years, the desired goal is extremely attainable.

This method of molding operates at a much higher efficiency because it hardly takes any time and the accuracy is insurmountable to other processes. The mold can be made to the customer’s exact specification and pre-programmed ensuring everything runs smoothly throughout.

For companies that would like to use multiple types of plastic or incorporate recyclable items into the product, co-injection would then come into play. Commodity, engineering, and high-performance resins can be chosen from, but they vary with cost. Some of the materials you will find with MP Manufacturing includes Acrylic, ABS, PS, Nylon, PVC, etc.

Because most of the labor is handled with machinery and robotics, the overall process is automated. Reducing the amount of labor force allows the general cost of manufacturing the parts to be severely decreased. Lastly, with the pre-programming and specifications known in advance, the injection process is extremely accurate and precise compared to other competitive methods.

We offer plastic injection molding for more substantial projects for the automotive, LED, medical and electronic industries that need products ranging from 90 to 1200 tons. Aside from the initial injection molding, we also offer painting, vacuum metalizing, laser welding, and more. If you would like more information about our company, explore our website!

What Goes into The Process of Design for Manufacturing?

Design for Manufacturing Graphic

The primary purpose of Design for Manufacturing (DFM) is to reduce the costs for overall part production. Usually, the methods used to minimize the complexity of manufacturing and use common processes. Throughout the product development process, design for manufacturing is a development practice emphasizing manufacturing issues. Successfully doing so results in lower production cost without sacrificing product quality.

5 Principles Stand Out in the DFM Process


Certain principles go into examining the DFM process. The process requires consideration of the number of products being made, what material is going to be used, the intricacy of the surfaces, the appropriate tolerances, and if secondary processed need to follow.


Once the process is finalized to make the product, the plan must be considered according to the type of product being manufactured. Discuss with the contract manufacturer to ensure that the chosen design corresponds to the right doctrines for the process selected in the first step.


Materials need to meet a specific criterion to showcase optimum use for the product. Consider how strong the material needs to be if it needs heat resistance, the electrical requirements, and how flammable it is before finalizing a decision. If the contract manufacturer has access to some of the materials you already have in mind, it will promote lower material pricing.


The environment in which the product will be used plays a significant role in the design process. Predicting what the typical use the product will endure are taken into consideration. Regardless of the way the product is formed, if not tested for what it may be subjected too, it will not withstand its expectancy.


The last main point to consider is if the product is compliant and can survive rigorous testing. The standards could be internal of the company, or overall industry standards ensuring the product is safe and is of high quality.
