The Four Most Important Ways And Advantages Of Plastic Production

Plastics production is one of the largest industries today. From packaging materials to heavy industrial components, there is widespread use or plastic. For a general release, most children or plastic materials look the same. However, their raw materials and the process of making plastics can vary greatly. The following are some of the plastic molding manufacturing processes and their benefits.

Injection molding

Injection molding is one of the most common methods used by plastic makers or manufactuers. The biggest edge of plastic molding is its cost-effectiveness. Plastics companies can produce large-scale products at the lowest cost. It also produces the least amount of waste, making it an ideal process for plastics companies. From small kitchen appliances to large bathroom fixtures, this process is suitable for any child or plastic profile.

The process

The process is very simple. The resins are heated to their melting point. They are then inserted into the mold. The molten plastic is extruded into a mold. The ideal process for large quantities of material at a low cost. However, preparing the form is very expensive. This procedure is not feasible if the quantity of goods required is low.

The blow Mould

This is a highly adaptable process in the plastics industry. It is commonly used in the manufacture of bottles, containers and other types of hollow lengths. This is a quick and inexpensive process for making thin-walled hollow shapes. You can use this process to get complex shapes.

The process

In this process, air pressure is applied to expand the molten thermoplastic to the desired shape. This is a good process for achieving seamless hollow shapes.

Custom plastic extrusion molding

Unique plastic extrusion is an ideal method for producing plastic profiles with strict tolerance. You can work with different materials and shapes using the unique plastic extrusion method. Accuracy and consistency are the plus points of the method.

The process

The plastic resins are melted and passed through a tool. You can get fixed plastic molds with the desired IDs and ODs. You have total freedom in choosing the shape and size of your material. The process uses templates and tools, so it is very cost-effective if your order volume is high. The preparation of extrusion tools and implements is expensive, so it may not be feasible to continue with small order size. However, if accuracy and consistency are key requirements, this is the process for you.

Rotating Mould

The rotational molding method is also used to make hollow objects such as injection blow molding. The raw materials used in this process are different. It uses plastic resins instead of plastic powders. Nylon, ABS, polyethylene, and PVC are the most common materials. This is an ideal process if you want to create large, hollow or concave shapes. It produces seamless and stress-free finished products. The process uses simple and inexpensive tools, but the tools need to be replaced frequently. The finished products thus obtained are of average quality and are not an ideal process for precision molding.

The process

In this process, the plastic powder is placed in a mold and heated in an oven. When hot, the mold rotates continuously to facilitate a thorough coating of the inside of the mold. After the mold has been removed and cooled in a controlled environment. Both the heating and the cooling process must be controlled with great precision as rapid temperature differences can lead to bubbles and spheres.

Plastic mold manufacturers also employ a variety of other methods, such as vacuum forming, extrusion, and thermoforming to produce plastic profiles. The choice of process depends greatly on its form, texture, and quantity of the order. 

Using Liquid Silicone Injection Molding for Security Systems

There are lots of uses for rubber keypads. One of them is security system controls. Whether commercial or residential, there are a number of factors that these should be used instead of plastic or touchscreen models. While there are 4 different types of rubber molding processes, liquid silicone injection molding is the most successful way to make long-lasting rubber keypads.


Use of backlighting on the console make sure the user can find the numbers in the dark. A backlit rubber keypad, this means that each key is illuminated, making it simpler to view. Using plastic buttons or a glass touchscreen get rid of the uncertainty. Pressing the right buttons when setting or disabling an alert system is important. When the wrong key is hit, this could cause a false alarm or fail to arm the system.


Durable printing is vital for rubber keypads. When numbers wear off after repeated use, any person coming to the office or home with nefarious intentions can simply determine the possible mixtures of the security code by examining the buttons. Liquid silicone injection molding with laser printing number on the keypads exteriors make sure it will not wear off to give away the code. Another choice is to use reverse laser printing on the underside of the key. The number is still perfectly visible, but the printing does not wear.

Touch keys

When dressing the different keys on a liquid silicone injection molding rubber keypad, the key has 2 objectives. There are various depths that a key must travel in order to serve its objective. The shape, size, and depth are determined in the design phase. Most vitally, each key must make contact with the security alarm panel device below to activate the right response. Secondly, the user should feel some give when they press the key to stop confusion. Imagine pressing the same button twice when attempting to add a code rightly. Improper code entry cause the alarm to tour. Failure to set the arm could make the chance of a security breach.


The liquid silicone injection molding process provides durability where plastic and other surfaces do not. Hard plastic can become extremely brittle in high temperatures. Liquid silicone injection molding is more durable in great temperatures, which means that the rubber keypads will last longer and can withstand more rugged situations.

Stack molding for plastic injection molding

Stack molds are some of the remarkable production tools to be found anywhere. The craftsmanship and engineering that goes into a stock mold is really  marvel.

For the layman, who has never built a plastic injection mold, it might look like a fancy, huge piece machinery that generates plastic widgets. Yet, from the perspective of an plastic mold maker, stack molds represent an extremely high level of expertise.

What is a stack mold?

There are different variations on the theme of stack molds, but some general specs are:

  • Built for extremely high production runs
  • Have a one cavity and different cores
  • Use indexable cores to injection and mold multi-materials
  • Have the capability to do different operations in the molding cycle

Basically, a stack mold has a stationary “A” half, and at least 2 “B” or moveable halves. They are alike to the rotary molds that have been in use for many years, but are vertical rather than horizontal.

This means that the portable cores rotate about a vertical axis, rather than a horizontal. Also, the stack mold is extremely compact and has a much little footprint.

What are the applications of stack molds?

Because they are top production products, the general applications are for consumables and cosmetics, such as toothpaste or deodorant containers. Medical and automotive products are normally produced using stack molds.

More and more items are being designed to use soft overmolding, such as hairbrushes or toothbrushes. These are best applications for stack molding. Because the part is plastic molding parts, chilled, overmolded and ejected in sequential cycles, production costs can be reduced.

What are the advantages of stack molding?

Stack molds are accessible in different configurations to meet a big range of molding demands and Cosmetics injection molding. Stack molding provides an economical and perfect manufacturing solution for the production of multiple plastic molding parts. Injection molding china firms are forever looking for more perfect way of molding and for the right.

A few of the advantages of the stack molding process contain: increased output efficiency

  • Reduces number of machines needed
  • Lower machine size need Vs. multi-cavity single face molds
  • Generate twice as many parts without rising press size or clamp tonnage, which greatly decreases part costs
  • Set-up time and run-time cost are divided by all the parts generated
  • Producing the back and front parts of a key fob at the same time is a best example of an application of stack molding
  • Mold ejection functions are self-contained, no extra labor or steps needed.

Composite Moulding

An eggshell is perhaps the best-known natural composite.

Composite materials are basically highly engineered combinations of polymer resins and reinforcing materials such as glass fibers that are incredibly strong, durable, flexible and non-corrosive.

The term “composites” is used broadly to describe a large range of materials that have generic reinforcement. These are combined with various resins that can be used for a large number of applications and are thus ideal for highly engineered materials targeted at specific applications. They are rapidly replacing products made the more traditional way from alloys and other metals. As raw materials become more expensive, so composites become a much more attractive and cost-effective proposition.

The expertise of MTM Plastics is in composite moulding. Examples of this type of technology can be found in many different industries today. Aviation is one such area that has embraced composites technology, with over 57% of aircraft components being made by this process. The Mass Transit industry, globally, also has taken the composites philosophy on board. If you travel today anywhere in Europe by train, the seats you sit on may well have been manufactured by MTM Plastics.

Durability, weight and corrosion are the three main advantages of choosing composites. Compared to steel and aluminium and based on density, composites have a superior stiffness-to-weight ratio. Given the same strength they are lighter than steel by 80% and aluminium by 60%. Many composites withstand continuous high operating temperatures up to 250˚C (482°F), and are highly resistant to corrosion.

The non-reactive nature of many resins and reinforcements can be custom-selected thereby resisting decomposition and degradation in chemically corrosive environments.

Durability is also a plus – well-designed composites have exhibited apparent infinite life characteristics, even in extreme environments.

Economically they make more sense. Composites offer designers an increasing array of choices through the vast range of materials on offer. The trend to use composites is highly favourable, especially when comparing the cost of fabrication. Our process allows the formation of a component in a single pressing, guaranteeing repeatability and consistency. This combined with lower initial start up costs and durability makes composites the right choice for many applications.

Improved safety.
On worksites, the electrical insulating properties of composites are inherent (depending on reinforcement selected). Alternatively, composites can be made to conductor selectively conduct electricity. Tunable energy management characteristics, with high-energy absorption or high-energy conductivity, are also possible. Made to Measure thermal expansion properties can be compounded to closely match surrounding structures to minimize thermal stresses. Composites have such exceptional shaping and forming properties they are more comparable to the proverbial ‘putty’. They can be made to almost any shape during fabrication. The composites’ inherent shaping and forming characteristics allow production to be established for a fraction of the cost that would be required in a metallic fabrication. Even in extremely harsh environments, well-designed composites have shown such infinite life characteristics they may well last an eternity.
