Several factors can influence plastic parts’ prototyping costs. These factors include the preferred material, the part’s complexity, and the chosen fabrication technique. Although 3D printing is often less costly than CNC machining, injection molding is relatively more expensive than the 3D printing processes and CNC machining due to mold milling costs.

This guide discusses the comprehensive guide to plastic prototyping. You’ll learn everything about the significance of plastic prototypes, plastic prototype development, methods for plastic prototyping, costs, and essential tips. Let’s get to it!

You can develop your master models for vacuum casting operations using CNC machining or 3D printing. Then, you have to create silicone-based cutting molds after completing the master model. You’ll have to inject the molten plastic/raw material into the mold cavity using a vacuum bell jar. The mold parts usually take 30-40 minutes to solidify to create a prototype replica.

Besides, plastic prototype manufacturing allows manufacturers to engage potential investors and customers. They can test these prototypes themselves. As such, these plastic parts prototypes help you gauge your potential customer’s interest in the product before launching.

Since prototypes have varied quality requirements, choosing the ideal plastic prototyping method for your applications is essential. Although your prototypes and production parts can have an approximate resemblance in the early stages, both must match closely when development approaches launching. As such, here are critical considerations for effective plastic prototype production:

Therefore, ensure you choose a method that offers prototype parts with the final product’s exact colors, geometry, and surface finishing.

Additionally, plastic prototyping allows product designers to optimize or modify designs with prototyping companies before plastic machining. As a result, it mitigates risks of design errors and failed prototyping, ensuring the production of functional plastic prototypes.

A PEEK plastic CNC machine is the second most common type of PEEK processing. CNC, or computer numerical control, is the automated control of machining tools by a computer. CNC machines process materials by following a coded programmed instruction instead of a manual operator.  CNC machined plastic is made by machining in the mass of a plastic block by milling machines with 3 axes with digital control. PEEK CNC machining is popular because it is the most efficient and economical option for the rapid production of prototypes and plastic models. The automated CNC machine is controlled by a computer that determines the path of the machine cutter according to the 3D file created. No molds are needed in CNC machining, therefore reducing startup time and costs. CNC plastic machining is ideal for parts larger than 600mm.

If you know that you are in need of processed PEEK plastic, consider reaching out to PEEK plastic manufacturers. Injection molding companies in Ohio will know exactly how to transform your exact PEEK material into the durable part that you need. Companies that specialize in CNC machined plastic can produce PEEK plastics of larger sizes and in more quantities.

The CAD model creation is a fundamental requirement in plastic prototype development. The Computer-Aided Design (CAD) model digitally represents your proposed plastic part. It portrays how the plastic parts should appear.

Prototype plastic injection molding forms the base for subsequent molds needed to complete your production runs. Industries such as medical, consumer goods, automobiles, electronics, and packaging utilize injection molded parts.

Plastic has evolved tremendously since its first uses in society, and every day, new uses and modifications are discovered. In today’s advanced world, engineered plastics such as PEEK are sought after to replace metals and increase the performance of certain parts.

PEEK plastic, also known as polyether ether ketone is a high-performance thermoplastic polymer. PEEK plastic is available in blocks, rods, powders, or pellets. Many parts made from PEEK are found in environments where temperature or chemical exposure poses a problem. PEEK plastics are not designed for every day or generic use. They are specially engineered plastics that are designed for very specific applications.

The plastic parts’ size and volume significantly influence the product’s final cost and lead time of the prototyping process. The intended prototype’s total volume significantly influences the choice of the ideal prototyping technique.

Therefore, it is evident that these plastic prototyping techniques have comparable costs, which depend majorly on the method used and the required volume.

This plastic prototyping process allows you to imitate as many plastic prototypes as possible. It uses a master model to form parts that are perfect for testing. When you use the vacuum casting technique for your plastic prototypes, you must inject molten plastic (raw material) into a silicone mold to form the prototype. However, it would be best to make a master model before creating your silicone molds.

Injection molding is the ideal fabrication method whenever you need limited plastic parts prototype production runs. It offers valuable ways of manufacturing prototypes despite being a popular method for full-scale production. The injection molding technique includes the creation of a metal die. You must mix the plastic resin into a heated barrel and forcefully inject it into the metal die.

CNC machining is an effective and fast-paced plastic prototyping method. It utilizes multiple tools to create 3D models of your design from solid blocks of materials. It uses a subtractive process to create prototypes. That is, this technique operates conversely to 3D printing. It removes material from the solid block, unlike the additive 3D printing process. Nonetheless, it doesn’t mean you cannot create plastic prototypes with varied materials.

Due to their strength, durability, and functionality, plastic product designers often make prototypes using nylon, ABS, acrylic, polycarbonate, and polyphenylsulfone.

Certain processes may have higher initial setup and tooling costs while they make inexpensive parts. Conversely, other techniques may require lower startup costs but higher part costs due to lesser automation, slower cycle times, and labor costs. The costs of such processes only reduce marginally, even with increased volumes.

Depending on the chosen materials, you can make plastic prototypes with greater strength and resolution with industrial-grade FDM printers. Additionally, FDM 3D is a flexible procedure well suited to various materials such as polycarbonate, PLA, Nylon, ABS, PETG, etc.

Plastic prototyping is beneficial to plastic product development because it facilitates the stimulation of the final product features. Therefore, it is easier to test the product’s functionality and the design’s correctness before mass producing the product.

A CAD model illustrates how the plastic components assemble and function. Preparing a CAD model for your plastic prototypes helps you to make a physical prototype model that is either visual or functional.

The design form and complexity may include intricate internal features and tight tolerances. As such, these factors help to decide the ideal prototyping technique for your prototypes. It would be best to note that the geometry of designs often limits some manufacturing options. They may require high-level Design for Manufacturing (DFM) optimization to be cost-effective or economical at best. The ideal choice is to choose technologies that can effectively match the intended geometry of your plastic prototype.

Rapid cooling of the plastic injection molds into a solid component is the last step of the injection molding process. It offers a prototype with outstanding mechanical properties and a high-quality surface finish. Injection molding is compatible with common thermoplastic materials like Nylon, ABS, Polycarbonate, Polyethylene, etc.

Plastic prototyping is among the versatile methods of rapid prototyping. You can choose the ideal procedure to produce prototypes from the range of available manufacturing processes. Here are four of the effective plastic prototyping methods:

3D printing or additive manufacturing comprises various manufacturing technologies. It is one of the cutting-edge prototyping techniques following the advent of Industry 4.0 that revolutionized the manufacturing arena. 3D printing is an umbrella term, as stated earlier. Below are three of the most common techniques for 3D prototype plastic parts fabrication:

Prototyping is a resourceful design process for many entrepreneurs and manufacturing businesses. As such, plastic prototypes are used for various applications across industries. Product designers rely on plastic prototypes to physically assess plastic parts before initiating mass production. These plastic prototypes help you study your plastic parts’ physical representation without delay.

ABS (Acrylonitrile Butadiene Styrene) is an easy-to-use thermoplastic commonly used in filament form. It exists in powder form for SLS (Selective Laser Sintering) processes. More importantly, it is one of the most cost-effective and accessible materials for 3D printing.

Plastic parts hardly get the deserved credit for the role played in product manufacturing despite being everywhere and having multiple applications in various industries.

The vacuum casting method works well with an extensive range of materials, ranging from opaque to transparent. Moreover, you can reuse the silicone-based casting molds to make about 25 plastic prototypes. This technique facilitates faster design actualization and ensures the close proximity of your product development and mass production.

SLS technique utilizes a high-powered laser like SLA 3D printing. However, it forges powdered materials together to create a 3D model. It offers a superior print quality compared to the FDM 3D technique. You’ll discover that plastic prototypes made using SLS 3D have higher resolutions and are more functional. As such, they are usually more durable and flexible compared to FDM prints.

Your plastic prototype’s application should be your initial consideration when producing plastic prototypes. Product developers usually use plastic parts in various industries and for varying purposes. Your plastic parts prototype might be for functional testing with prospective consumers. Conversely, you might need the prototype for non-functional testing for marketing or sales.

3D printing techniques have low fixed costs, ensuring zero economies of scale. Moreover, the first imitation has the exact cost as the last copy. Likewise, CNC machining has low fixed costs, with total costs increasing steadily. So, the cost of each part will be a little higher than the similar parts created with 3D printing. The cost of the first few parts is relatively high, as in the case of prototype plastic injection molding. However, the cost reduces gradually as the volume increases.

SLA 3D printing uses plastic resin materials to make 3D plastic prototypes. It employs a high-powered laser to solidify the model. This technique can be used for prototyping medical, dental, and general consumer electronics applications.

PEEK plastic is processed through an injection molding machine and unique molds to form raw plastic materials into the parts you need. The plastic is melted into the injection molding machine and then into your customized mold. Once the plastic cools and hardens, it’s transformed into a strong and durable plastic part for your project or industry. For PEEK injection molding Ohio, processing temperatures ideally need to be somewhere between 662°F-752°F. For the best PEEK injection molding process, it is crucial to keep the PEEK plastic clean and dry. If your PEEK plastic is in pellet form, you can dry them on trays that circulate in an oven for 2-3 hours. To keep your PEEK plastic clean, keep any contaminants away during PEEK processing. For the best PEEK injection moulding performance, additives found in PEI plastic can be pre-compounded into PEEK plastic to make it ideal for injection molding.

However, how soon you need your plastic prototype may determine your choice of a rapid prototyping technique. Some methods use cutting-edge tooling with automation to achieve plastic prototypes within 24 hours or less. Unfortunately, the tooling and setups for some methods could result in weeks as lead time. Therefore, choosing the process that creates parts quickly is advisable if you need to test your plastic prototype quickly.
