"The best service and quality for the right price! Really professional and always trying to help the customer! Definitely great!" - Daniel Climber

"Accurate delivery times and fast service. I have been very satisfied with the parts that I have purchased." - Tony Lazaro

"Excellent service and fast turnaround at a competitive price. Items were delivered to our office in New Zealand within 1 month of placing the order, and all parts were within design tolerances." - Corben Taylor

"Great platform for CNC Machining. I ordered some parts to be CNC machined in Aluminum 6082 for a prototype build I am working on. Drawing was finished Tuesday, January 5th, and sent to my regular machining shops nearby. This time I also uploaded a STEP file of the design to partZpro to test their system after finding them on the internet. On January 6th, I received a quote for shipping and manufacturing. I was surprised by the easy process on their website and ordered the parts to test it out. A few days later, I sent an address update to sales to add some information for transport. Unbelievably, on the morning of Monday, January 11th, DHL was at my doorstep delivering the parts. Shipping had the updated information. We are talking about less than 4 working days, delivered from the other side of the world, and that's before my nearby shops had even responded with their quote and lead time. The parts delivered were a perfect fit, better than specified tolerance, and had a great surface finish. I will definitely look into this service when I need parts next time." - Rune Kvamme

"I recently used PartZPro for a prototype to be made from a 3D file into aluminum. I'm super happy I did. Cost was a fraction of its competitors' and turnaround was about a month, during holidays. Parts were very accurate and now my prototype is one step closer to being finalized. Will most definitely use again." - Matt Faxon

"Response time is incredibly fast. I am impressed, and it adds to their credibility. Will do business with them again ASAP." - Mark Scallan

"Great job on products that I have ordered." - ASG Astrology

"Great service, pricing, and speed." - Paul Murtagh

"Parts are always made to your design specifications. Reasonable prices and fast turnaround." - Dennis Tang

"A very prompt quotation and efficient processing of our order. CNC machining was executed exactly as requested. Delivery was pretty fast, even faster than quoted." - Andre Dussault

Industries that have the most use for plastic injection molding

Plastic injection molding has grown to be the most popular molding technique. The process used varies in a wide array of ways, including but not limited to applications. To wit, here is some top industries hat apply this molding technique in their operations.

Food and Beverage 

For optimal human health and the safety of people, the food and beverage industry has some of the highest standards in the world – as is appropriate.  Regulators ad companies require that food and beverage products be compliant with various specifications, including freedom from BPAs, toxins, and GMAs. To help with this, plastic injection molding companies can manufacture different food-grade materials. The ideal partner for a food and beverage company will be compliant with HAACP (Hazard Analysis Critical Control Point) regulations and being GMA-safe.

Food-grade injection molding services can be used in processing and packaging applications such as:

  1. Components for beverage filtering applications 
  2. Containers and packaging tools for food and beverages
  3. Beverage caps
  4. Components for food processing

Medical & Pharmaceutical

The medical and pharmaceutical industry is one of the most valuable in the world. Given the significance of the tools provided here, it is essential to achieve higher levels of reliability and quality. People’s lives are at stake here, and it is essential to consider the liability and the traceability of full parts. 

There have been various improvements in the design of medical equipment, and plastic injection modeling is another area that has seen considerable growth over the years. With engineering-grade plastic resins, companies can achieve better mechanical properties. These include resistance to high temperatures, greater tensile strength, and higher levels of force tolerance. Given the demanding nature of medical assemblies, these are quite impressive.  Apart from its ability to reduce part weight, plastic injection molding can also reduce lead time, material waste, and the overall cost of manufacturing. The technique can also help to improve design flexibility and optimization. Several manufacturers work with an uncolored virgin material, which helps to incorporate different part colors and design styles that can meet clients’ custom needs.

Some high-quality medical parts that can be manufactured using plastic injection molding include: 

  1. Components for dental x-ray machines
  2. Surgical preparation kits
  3. Diagnostics test tools 

Windows & Doors 

Injection molding companies also do quite a lot of work for door and window manufacturers. Most of them work on designing and developing custom parts for window users that are up to application specs and standards.  With the right injection molding company, you could quickly get some high-margin, low-cost solutions to part manufacturing as well.  At the same time, it is essential to get parts that have optimal wearability and thermal properties. Some of them include Celkon, UV inhibited engineered nylon, vinyl, polypropylene, and several other custom options. Apart from improving longevity, these materials also ensure that the doors and windows are up to standard.  Using injection molding in the window and door industry comes with quite a lot of advantages. With plastic resins, you can achieve the same components of costlier metals and also eliminate the risk of corrosion and rust – mainly when used in favorable environments.

Some other benefits of injection molding for windows and doors include: 

  1. With redesigned parts, you can reduce costs and cut the assembly process
  2. High-reliability resins can replace metal parts, and they cost less
  3. Plastic spring application will reduce the incidence of corrosion and rust

partZpro Frequently Asked Questions

The "Open-Book" Business Model

Q: Why is there a factory invoice in the box?
That is your Commercial Import Invoice. Because we ship Factory Direct to your door, international customs requires an invoice that travels with the package.
  • Transparency & Compliance: This invoice lists the origin factory (showing you exactly who made your parts) and declares the exact value you paid at checkout.
  • Why it matches your payment: We ensure the commercial invoice matches your transaction value so that Customs calculates your duties correctly and legally, preventing delays or penalties at the border.
Q: If I have the factory’s info, why shouldn't I just go direct next time?
You can, but our clients stick with us for the "US Shield." When you order through PartzPro, your money is held in a US-based Escrow until the parts are delivered and verified. If you go direct, you are sending money overseas with zero recourse. We handle the legal leverage, language barriers, and financial security to ensure the factory prioritizes your job over others.
Q: What exactly does your Service Fee cover?
Your fee covers Financial Security (Escrow), Vendor Vetting, AI Engineering Analysis, and Project Management. We act as your US-based legal firewall. We find the best factories, negotiate the rates, and hold the money until the job is done right.

Logistics, Customs & AI Technology

Q: Who handles the HTS Codes and Customs paperwork?
Our AI does the heavy lifting; you just confirm the release. We don't leave you guessing on complex government tariffs.
  • Heavy AI Analysis: Our proprietary AI Assistant performs a 40-point analysis of your part's geometry and material. It automatically searches the official US Government HTS database to generate a precise HTS Code Breakdown for your specific parts.
  • The Process: This data is provided to the carrier (DHL/FedEx/UPS). When the broker contacts you, the classification is already estimated—you simply confirm it to release the shipment.
Q: Who pays the duties?
You do—which saves you money. Because we ship DAP (Delivered at Place), you pay the exact duties owed to the government based on the AI-generated HTS code.
  • Why this is better: Competitors who offer "Free Shipping/DDP" often inflate the price to cover the worst-case tariff scenario. By paying the actual duties yourself, you ensure you are never overcharged for import taxes.
Q: How fast is shipping?
Since we skip the "Middleman Warehouse," our standard international shipping is extremely fast (typically 3–5 days transit). Your parts fly directly from the machine shop to your desk.

Quality Assurance & Liability

Q: Competitors inspect parts at a US warehouse before shipping. Why don't you?
Because "double handling" kills speed and adds unnecessary cost. We operate on a "Dock-to-Stock" model. The factory performs the rigorous QC, and parts ship directly to you.

We treat you like a professional: we know you will verify the fit and function of your parts upon arrival. By removing the redundant middleman inspection, we save you 30% on cost and 3–5 days on lead time.
Q: What happens if the parts arrive out of spec?
You are protected by the PartzPro Escrow Guarantee. Because we hold the funds, the factory does not get paid until you are satisfied. If parts are non-conforming, simply upload a photo and inspection report. We will either force an immediate priority remake at the factory’s expense or issue a refund. You stay in control.
Q: Does your AI just check for geometry errors?
No. Our AI Cost-Driver Audit goes beyond simple DFM (Design for Manufacturing). It helps you perform Value Engineering by highlighting features that are disproportionately expensive (e.g., deep pockets, tight radii, non-standard threads). We show you the cost drivers so you can engineer the price down before you order.

Payments & Corporate Orders

Q: We are a company, not a hobbyist. Can we pay via Purchase Order (PO)?
Yes. We specialize in serving agile engineering departments and mid-sized manufacturing firms.
  • How to order with a PO: You can select "Pay via PO / Wire" at checkout or email our sales team directly with your PO attached. We will verify your company details and send a payment link or wire instructions immediately so production isn't delayed.
Q: Do you offer Net-30 Terms?
We offer terms to qualified business partners after an initial credit review. Please contact our sales team to set up your corporate account. For new customers, we recommend using our PO-to-Wire workflow for the fastest start.
