We excel in creating production-equivalent plastic components through our successful design and fabrication of thousands of prototype molds, all produced in-house. Unlike other prototype molders who may struggle with complex part geometries and reject them, we have the expertise and equipment to mold even the most challenging designs that push the boundaries of injection molding rules.
How Do We Do It?
Premium Prototype Molding Solutions
Professional Moldability Review
Unlike many prototype molders, we do not feel that an automated moldability review of your part model is sufficient. We prefer to provide a more personal and professional design review over Zoom with the goal of improving molded part quality while also minimizing cost and lead time. Clients can ask questions and fully understand our recommendations. The result of this collaboration is an improved part model ready for prototype molding that will meet your product requirements.
High-Quailty CNC Machine
We invest in high quality CNC mills that are typically used to fabricate production molds. It’s overkill for prototype molds but necessary for achieving our goal of replicating production mold quality. The higher quality CNC mills also allow us to machine molds faster without sacrificing accuracy due to their improved spindle rigidity and cooling.
Superior Customer Experience
In addition to the personal moldability review we have invested in a website that significantly improves the prototype molding process for our customers. With our website you can get real time status updates, track shipping, order additional molded parts or mold iterations, and view the complete history of your projects including quotes, packing slips, and inspection reports.
Superior Molding Processing
Our prototype molding system allows for both heating and cooling of the mold, similar to production molds. As a result, we’re able to create a molding process that yields significantly improved part quality. Critical dimensions are more accurate with tighter tolerances compared to other prototype molders
How The Process Works
Upload part model for prototype mold quote
Mold fabrication completed
Mold sampling (25 ea) and client review
Order prototype parts as needed
Request rapid mold iterations as needed
Typically 1 week, we will indicate the lead time when we provide your quote.
Maximum Part Size
Part may be up to 8″ x 6″ x4″ (200 x 150 x 100 mm)
Maximum Part Volume
Shot volume up to 6 oz (170 g)

If you’re looking to propel your business to new heights, don’t hesitate to explore how plastic injection molding can benefit your company.
Protoshop can be a great resource if you need to design and produce plastic components using state-of-the-art plastic injection molding procedures. Our team is composed of skilled experts who have experience in engineering, design, mold fabrication, manufacturing, and management.
Rapidly Replicate Prototype Molds at the Highest Quality
We make all our molds using Arburg injection molding machines that are built in Lossburg, Germany. Our goal is to replicate production molding as closely as possible and using a production quality injection molding machine is critical.
Testing and development using a high quality prototype part that closely replicates production makes transfer to manufacturing an exercise rather than a step involving risk.
Hear From Our Satisfied Customers
We work regularly with Protoshop on a variety of complex components for various projects. They are an excellent company to work with providing a vast history of experience to help their clients optimize designs. We have worked with them on microfluidic chips with small feature sizes, over molded sealing parts and flexible parts. They have experience working with many materials including Topas (COC), polycarbonate, TPE, PE, and PP. I would highly recommend reaching out on your next project. The team is very responsive to design changes as well as delivering to tight timelines. They also offer design advice and best practices which have helped expedite design iterations.
- Garrett G.
Dylann and team are wonderful to work with. On multiple programs, they have delivered quality product in a matter of days. The design for moldability support is unparalleled to ensure your part is ready to order.
- Chad F.
Having worked with Dylann and Jimmy prior to Protoshop, I knew the immense level of expertise they have for this business and it proved to carry through. They are honest straight shooters that will help guide you and find the best solution for your molds. We needed a mild that could be versatile and allow us to easily change out one side of the design. Dylann helped us come up with an approach that will allow us to continuously iteration the design without having to make a whole new mold every time.
- Stacie D.
Dylann at Protoshop is excellent to work with: highly responsive and proactive. This is possibly the fastest, high-quality work I have ever witnessed. 1 week…from payment (start) to delivery (after CTQ measurements at Protoshop), we had 100 test samples of a component we intend to use in high volume manufacturing. Thank you for the tremendous work! I would highly recommend Protoshop, and will plan to use Protoshop services in the future.
- Wendell W.
Great experience with Protoshop. Dylann is extremely responsive and great to work with. Very fast turn-around. Worked with us on our order to get what we needed. I was able to drop ship 3d printed parts from another vendor to Protoshop to have them match-fit and incorporated into our tooling. I will be back again.

Proprietary Plastic Injection Prototype Molding Method.
Plastic injection molding is the process used to create the plastic parts that are used in most of the products you use every day. Plastics are used in a wide range of applications, from simple buttons to complex implantable medical devices visible under x-ray and everything in between. This is why plastic resin manufacturers offer over 60,000 grades of plastic. Plastics are well suited for manufacturing due to their relatively low cost per part, part consistency, and ability to fabricate large numbers of parts quickly.
The basic principle of injection molding hasn’t changed substantially since it was first patented in 1872. Over the last 150 years, innovations have involved the addition of electronic control and automation of the molding process. Our plastic prototyping service consists of two essential parts: an injection unit and a clamping unit. The injection unit is where the plastic resin is added to the machine, and heat is applied to change the plastic resin to a flowable liquid state. The clamping unit contains the mold.
The mold is a machined assembly that contains the part detail to be molded. Once the mold is split into two sections, it allows the clamping unit to open and close the mold as needed. In order to mold a part, the clamping unit closes the mold, and the injection unit pushes the liquid plastic into the mold. The plastic quickly cools. The clamping unit opens the mold, and the part is ejected. The process then repeats.
