How Do You Handle Mold Development for Entirely New Shapes or Features?

At LOT (Prosundrinkware Co., Ltd.), we specialize in custom production of stainless steel insulated cups. When you need a completely new shape or feature, our mold development process is designed to turn your concept into a manufacturable product. We combine engineering expertise, 3D modeling, and rigorous sampling to ensure your custom design meets both functional and aesthetic goals.

Step 1: Consultation and Design Brief

Every new project starts with a conversation. We discuss your target market, functional requirements, budget, and timeline. Whether you need a new water bottle, tumbler, mug, or food jar, we review your ideas and assess feasibility. If you have sketches or reference samples, we use them as a starting point. We also have 17 customizable 3D models available that can be adapted or used as inspiration.

Step 2: 3D Modeling and Engineering

Our engineering team creates detailed 3D CAD models of your new shape. We pay close attention to critical factors such as double-wall vacuum insulation, material thickness (we use 18/8 stainless steel for durability and rust resistance), lid mechanisms (like the locking lid on our LOT25-080 water bottle), and ergonomic features. We ensure the design is manufacturable and that it maintains key performance attributes like keeping drinks hot for 12 hours and cold for 24 hours.

Step 3: Mold Design and Fabrication

Once the 3D design is approved, we proceed to mold design. Our team designs the mold to ensure proper material flow, cooling, and ejection. We fabricate the mold using high-quality materials to withstand production runs. This step is critical for achieving consistent part dimensions and surface finish.

Step 4: Sampling and Testing

We produce initial samples from the new mold. These samples undergo rigorous testing: leak-proof performance, insulation efficiency, drop resistance, and overall durability. We also check that the new shape or feature functions as intended—for example, a new lid design must be easy to open and close while remaining secure. We then send samples to you for evaluation and approval.

Step 5: Modifications and Finalization

Based on your feedback, we make necessary adjustments to the mold. This iterative process ensures the final product meets your exact specifications. Once approved, the mold is ready for mass production.

Step 6: Production and Color Matching

After mold approval, we move to mass production. We also handle color matching to align with your brand. Whether you need a standard color like Blue or Orange (as available on our LOT25-080 model) or a custom shade, we can match Pantone references or physical samples. Our custom production services help you reduce costs, enhance product quality, and expand your market reach.
