At Gemini Plastics, Inc., we understand that when you’re developing a product or managing procurement, time equals money. Whether you’re finalizing a prototype or managing production deadlines, getting a fast, accurate quote for your custom plastic part is critical to staying on schedule and within budget.
To help avoid delays and back-and-forth, here’s what to include when you send us a request for quote (RFQ):
⸻
1. Describe the Part’s Function
A quick summary of what the part does helps us recommend the right material and production method. Is it load-bearing? Cosmetic? Part of an assembly? Context helps us ensure our quote is tailored to your needs.
Example: “This bracket supports a wall-mounted enclosure. It must be rigid and capable of holding 10 lbs.”
⸻
2. Include Technical Drawings or 3D CAD Files
We typically quote from customer-supplied files, so please include 2D technical drawings or 3D CAD formats (e.g., STEP, IGES, STL). These help us identify critical details like dimensions, tolerances, and features that impact production time and cost.
Don’t have a design yet? We’ve got you covered. Through our partnership with CADmore, we can connect you with professional design and engineering services. Once their team finalizes your drawings, we’ll receive direct access to the files for seamless quoting and production planning.
⸻
3. Specify Material or Performance Requirements
If you know the material, great. If not, just describe the performance requirements. Here are a few helpful considerations:
• Chemical, UV, or heat resistance
• Impact strength or rigidity
• Food-grade or medical compliance
• Specific color, texture, or finish
Not sure what plastic fits best? Just describe your needs—we’re happy to guide you.
⸻
4. Estimate Your Annual Volume
Knowing your expected volume helps us recommend the most efficient process, whether that’s rapid prototyping, short-run molding, or full-scale production.
Example: “We expect to order 1,000 parts per year, starting with 250.”
⸻
5. Share Your Target Timeline
Let us know your desired delivery date or critical deadlines (like product launches or tradeshow dates). The earlier we know, the better we can align production to meet your schedule.
⸻
6. List Any Secondary Services Needed
If your part needs additional work, like light assembly, labeling, or kitting, be sure to include those requirements. We offer a range of value-added services to streamline your production and packaging.
⸻
7. Note Packaging or Shipping Requirements
Have special packaging needs, barcode labels, or want us to ship to your fulfillment center? Let us know up front so we can include those costs and lead times in your quote.
⸻
8. Call Out Any Compliance Requirements
If your part must meet certain regulatory or certification standards (e.g., FDA, RoHS, REACH, ISO), we’ll ensure compliant materials are used and the necessary documentation is prepared.
