Rapid Plastic Prototyping:
For low-volume prototyping, we provide you with CNC machining, 3D printing, and vacuum casting. Each of them gets its strengths.

CNC Machining: It uses cutters to remove the extra material from the stock material until it becomes a part with custom type. The biggest advantage of CNC machining is its precision. The tolerance of plastic prototypes is around ±0.01mm.

3D Printing: It is a popular technology to create complex rapid plastic prototypes within days. Meanwhile, the surface of 3D printed parts is not as smooth as machined prototypes. We usually apply special sandpaper to polish the printed parts.

Vacuum Casting: It produces low-volume replicas by creating a silicone mold first. It is a cost-effective choice for creating plastic parts because of its low-cost mold and material. On the other hand, vacuum casting prototypes are of not tight tolerance. The over-used plastic prototypes are easily to expand and contract.

We are a fully equipped manufacturer with the 5-axis CNC machines, 3D printers, and vacuum casting machines to support your prototyping projects.

Plastic Prototype Molding:
If you need high-voluem plastic parts, injection molding is your best option. After the initiative prototyping stage by machining or printing, we will put the tested parts into mass production. We need to create the custom metal molds by machining and EDM first. These metal molds can be reused 100000+ times to create accurate and identical plastic parts.

4. How does the Plastic Prototype Model Works?

If you are looking forward to manufacturing your first-ever Plastic Prototype, you must have a CAD Model. This model is required so that the manufacturers get an idea of your product. To create this Computer Aid Design for your Plastic Prototype, you can also get help from professionals. The Plastic Prototype manufacturing works after you deliver this CAD model.

  • the Plastic Prototypes can be visual in which an idea of the final Prototype is delivered.
  • Or they can also be functional, which is more precise than the visual ones.
  • CAD Model Example
  • The functional Prototype allows you to go through your design before actually producing it. This helps you see how the plastic Prototype will look in real once it’s manufactured. In this way, you can change the model or design if it doesn’t look appropriate.

5. Which Methods Are The Best to Manufacture a Plastic Prototype?

There is a significant number of methods that can be used to manufacture plastic prototypes. Each prototyping technique has its own pros and cons. For instance, if you use the 3D Printing technique, it is beneficial and the cheapest way to develop a visual plastic prototype.

But if you are looking for a more enhanced and better technique to manufacture a functional prototype, you must go for the injection molding method. The strength of plastic prototypes depends upon how their molds look. The better the mold, the perfect the Prototype. And there is no better way to manufacture perfect plastic molds than the injection molding technique.

7. How Can You Use The 3D Printing Method to Manufacture a Plastic Prototype?

3D Printing is a broad term that includes a number of methods and techniques. There are multiple options that you can opt for in order to produce Plastic Prototypes with the 3D printing methods. So, do you want to know the best and most-liked options used in the world for manufacturing Plastic Prototypes through 3D Printing?

Well, the first one in the list is the,

SLS (Selective Laser Sintering) Process

  • Selective Laser Sintering

This technique does wonders when it comes to Plastic Prototype manufacturing. The material that is most widely used in this method is Nylon (PA 11 or PA 12). This method is used to produce the most superior quality plastic prototypes.

In the SLS method, a laser is used to fuse the powder together at low temperatures. It can also be known as Sintering. This powder is sintered into a 3D model, which is then used to manufacture the required plastic prototype.

As the prototypes produced by this method require a high-powered laser, their quality and resolution are nothing less than an elite prototype. If you are looking for a method to produce the most functional and durable Plastic Prototypes, then there is no better option than the SLS 3D printing technique.

  • Fused Deposition Modeling

This technique is not as good as the SLS 3D Printing in terms of resolution and strength but is still the most commonly used 3D Printing method. This method works by putting layers over layers until the Prototype is complete. Almost all Plastic Prototype manufacturers, businesses, and consumer communities prefer this technique over others.

The resulting strength and resolution ratio of the plastic Prototype manufactured by this method depend on the material/substance you used in the process. As this method is easily affordable and does not require much investment, the material used for this process is cheap, too.

The Process of Fused Deposition Modeling

If you want more of a colorful and pretty prototype, the best material for this purpose will be Polylactic Acid. The prototypes produced using PLA are not mechanically strong neither they serve any useful purpose. Such prototypes are only for decoration purposes.

But if you are looking for better functionality in addition to the colors, you can try using fused material too. For instance, you can mix up the PLA with wood or metal materials. This will help you enhance the mechanical functionality of the plastic prototypes you manufacture. Other superior materials, including carbon fiber, can also be used for this purpose.

  • Stereolithography

This technique is great as it does not require specific new materials to work upon. All that it needs is the resin plastic material. Stereolithography uses that material to produce new Plastic Prototypes. Like the SLS technology, this process also uses a high-powered laser. This laser turns the resin plastic into a solidified prototype model.

Stereolithography Process

The SLA 3D printing can be used for many distinct purposes. If you work in the medical or dental spaces, this technique can be greatly helpful to you in working. Furthermore, it is also highly suggested to manufacture different consumer goods and products.

These techniques are the 3D printing methods that are used to manufacture a wide variety of different plastic prototypes worldwide. If you are looking for such a method, you can either choose yourself from these three, or you can also contact a professional to help you out.

8. Can CNC Machining Be Used To Produce Distinct Plastic Prototypes?

Yes, CNC Machining is a very appreciable method to produce plastic prototypes of various kinds. In fact, it is preferred over Printing too. It is because, as compared to other methods, this technique offers more complicated designs with better finishing. Thus, you can make fascinating plastic prototypes using this CNC Machining method with more accuracy and precision.

The CNC Machining also makes it easier for you to test and try out the molds and your ideas without actually requiring the injection mold tooling.  The CNC Machining method does not only provide quality plastic prototypes, but it also helps you get them at lesser rates.

CNC Machining

The biggest reason behind this is it does not requires producing the injection molds. The injection mold tooling is super-expensive, even if you want to manufacture a small plastic prototype. Moreover, unlike other traditional methods, a lot of plastic materials can be used in CNC Machining production.

You can choose the one most appropriate for your plastic prototypes from a comprehensive list of materials such as POM, Teflon, ABS, PP, etc. Another benefit of using CNC Machining or Milling for the Plastic Prototypes production is quick delivery times. These methods do not require a lot of weeks or months to produce perfect quality plastic prototypes for you.

9. How Can You Use Injection Molding To Produce a Plastic Prototype?

Using injection molding is usually said to be more effective than the 3D printing method. At the same time, it is also more expensive than other methods. But if you are looking to produce some plastic prototypes with a quality finish, injection molding can definitely be a good choice to opt for.

The injection molding method is not very complicated or hard when it comes to producing prototypes. There are just a few simple steps that are involved in the entire injection molding technique. These basic steps that are followed to produce the plastic prototypes are as follow,

  • First of all, a metal die is created. It is basically a machine tool or a mold in which the material is put to form the desired shape.
  • Then, a heated barrel is used to properly heat up the plastic material/resin.
  • After heating and mixing up this resin, it is sent into the metal die. A force is required to inject this plastic resin into the die.
  • After injecting it, this resin material is cooled down immediately.
  • Cooling the resin material turns it into a solid part of the desired form and shape.

A high-quality plastic prototype is produced after following all these steps properly. This newly manufactured Prototype is said to have better finishing, resolution, mechanical functioning, and reliability than the prototypes formed by other usual methods.


10. Which Plastic Prototypes Should You Manufacture Using the Injection Molding Method?

The Prototypes produced using the injection molding methods never have to go through breaking or cracking. Its deformation happens without any hard molding processes taking place over the material. This makes the process a perfect fit for manufacturing medical and other delicate products.

These products may include lenses and essential devices used for medical purposes. You can also use injection molding to manufacture useful and quality automotive components. It is because those components are also needed to be manufactured without making them go through breaking or cracking. You can also watch this YouTube video to get an idea about a injection molding machine.

Moreover, the materials used in this injection molding process are more likely to produce strengthened and tough plastic prototypes. Such as the ABS material, Nylon, or Polyethylene, each material has its own benefits. And thus, it offers a wide range of different mechanical functions.

Injection Molding Tools

This makes you able to choose the material that is a perfect fit for the product you want to produce. Just make sure to choose the material that has all the required properties. For instance, if you are looking to manufacture a product that offers a high ductility rate, flexibility (tensile strength), and similar properties, you should opt for Polyethylene. It usually comes in the shape of either LDPE or HDPE.

11. What Are The Steps Involved In Plastic Prototype Manufacturing Using Vacuum Casting?

Producing plastic prototypes using vacuum casting is another beneficial method. You have to follow an array of steps in order to get a perfect plastic prototype from this method. Before describing the steps, you must know that this technique is usually profitable for small prototypes.

Coming to the process of vacuum casting, the major steps involved in this process are described as follows,

  • As described earlier, plastic prototype production starts with a CAD Model. Once you have that model, the Vacuum Casting process turns it into a master model or mold. This model is then used to carry the whole process. To create this model, you can either use CNC Machining or Printing.
  • Have you ever heard about silicon-based molds? Well, these are casting molds used in this process to produce perfect plastic prototypes. All you have to do is fill these molds with the resin. But make sure that the entire cavity present in the master mold is filled. Otherwise, your Prototype will not turn out to be perfect.
  • After the resin is dried out, it can be taken out as the final plastic prototype. This process is open to many types of materials that can be used as the resin. You can choose any substance that suits you according to your Prototype.

Vacuum Casting

Vacuum casting is mostly used for manufacturing prototypes that do not have much of any mechanical use later on. Some examples of the plastic prototypes manufactured by this method can be casings or small housing.

If seen as a whole, this process is beneficial as a single mold can help you manufacture up to 25 distinct plastic prototypes. Furthermore, the average turnaround time is normal too. Usually, this time stretches out to one week or two at max.

12.  Are Plastic Prototypes Durable and Reliable?

The plastic prototypes being produced nowadays are highly appreciable when it comes to strength, durability, and reliability. Their low melting temperatures make it easier for you to manufacture them without going through hazardous procedures. This not only saves your time but also your money and energy.

  • When it comes to durability, plastic is known throughout the world for its stability and strength. Furthermore, the beneficial chemical and frictional properties of plastic resins make the prototypes highly dependable and durable. However, you still need to take care of them.

Leaving these prototypes open to extreme temperatures, radiations, or lights can damage them. But if you keep them properly, there is no way the prototypes will not last long. They are made to be used for longer durations so that the owner does not have to go through the manufacturing procedures again and again,

  • Talking about reliability, these prototypes are greatly known for it too. The techniques used to manufacture plastic prototypes may cost a bit, but it is totally worth it. Whenever you produce a plastic prototype using a professional method and the right resin material, there is no way the product does not come out to be strong enough.

You can contact the professionals in order to choose the best material and ways for the production of your prototypes. Now, as the prototypes are made to be recyclable, it is good for the ecosystem too. You do not have to waste material or the earth’s natural resources in order to get the perfect plastic prototypes for yourself.

13. What Is The Usual Turnaround Time For A Plastic Prototype?

Normally, the turnaround time depends upon your product. But with the advancement and enhancement in technology, the turnaround times have become lesser. There are also some prototypes that you can get in just a few days. But that is only if your Prototype is a small and simple product. Otherwise, it does take time to be completed.

The injection mold tooling is known to be the fastest method. So, if you have a good budget and material, your order can also be prepared in just 2-3 days. But on average, it may take approximately two weeks.

There is never anything wrong with waiting, though. The longer time it takes to get your plastic prototype manufactured, the better quality it has.
