Custom leak-proof reusable tumbler for coffee chain

CASE 01 · FOOD & BEVERAGE

Zero-Leak Tumbler for Coffee Chains

Client Challenge:

Hot coffee vapor pressure was causing sip-lids on competing tumblers to pop open or weep along the screw threading during morning commuter walks.

Engineering Solution

We engineered a dual-chamber silicone pressure-relief valve integrated into the flip cap, combined with a reinforced trapezoidal silicone seal ring and heat-tolerant Eastman Tritan body (rated up to 96°C).

Deliverables & Results

150,000 units delivered across 120 retail outlets in 28 calendar days. Zero leakage complaints reported; full German LFGB sensory and migration certificates delivered.

Coordinated 4-size drinkware retail assortment

CASE 02 · IMPORT & RETAIL

Unified 4-Size Hydration Bottle Range

Client Challenge:

Supermarket buyer needed 16oz, 24oz, 32oz, and 40oz bottles on shelves, but managing 4 separate lid inventory lines created severe stocking friction and high tooling fees.

Engineering Solution

Standardized the neck diameter across all 4 bottle capacities to a single 63mm wide-mouth tooling spec. One master neck profile accepts straw lids, chug caps, and magnetic flip tops seamlessly.

Deliverables & Results

Reduced client tooling and spare-parts inventory overhead by 35%. Master cartons successfully passed ISTA-1A drop testing for supermarket pallet distribution.

Scratch-proof matte tumbler for Amazon e-commerce

CASE 03 · BRANDS & DTC

Scratch-Resistant Amazon FBA Tumbler

Client Challenge:

An online fitness brand suffered high Amazon customer return rates (4.8%) due to micro-scratching on tumbler bodies during courier parcel handling.

Engineering Solution

Formulated a scratch-resistant soft-touch matte finish with high abrasion resistance. Engineered an internal corrugated tuck-box insert with protective bubble sleeve and applied FNSKU barcode stickers inline at the factory.

Deliverables & Results

Return rate plunged from 4.8% to under 0.2%. Goods arrived directly at US Amazon fulfillment centers with zero re-packaging or labeling fees.

Fast-track branded stadium cups for live sports festival

CASE 04 · PROMOTIONAL CAMPAIGNS

80,000 Stadium Cups in 20 Days

Client Challenge:

An international music and sports festival required 80,000 durable, dishwasher-safe PP souvenir cups with vibrant 360° 4-color event artwork within just 20 days.

Engineering Solution

Leveraged existing multi-cavity open molds and mobilized three automated 360° heat-transfer printing lines operating on dual 24/7 shifts, completing pre-production sample sign-off within 48 hours.

Deliverables & Results

Split air/sea shipment delivered 100% on schedule 3 days prior to the opening ceremony. Cups fully complied with FDA food-contact standards and survived 50+ wash cycles.

Shatterproof commercial poolside drinkware for resorts

CASE 06 · HOSPITALITY & OUTDOOR

Shatterproof Resort Poolside Drinkware

Client Challenge:

Resort chain needed drinkware that looked and felt like heavy premium glass, but wouldn't shatter into dangerous shards on wet outdoor concrete pool decks or fog up after industrial washing.

Engineering Solution

Molded with premium Eastman Tritan TX1001 resin with thick-wall optical geometry and optimized annealing cycles, eliminating internal stress and optical distortion.

Deliverables & Results

Guaranteed shatterproof performance across 500+ commercial high-temperature dishwasher cycles with zero clouding, crazing, or chemical odor.

Proprietary fitness shaker cup with magnetic cap

CASE 07 · CUSTOM DEVELOPMENT

Patented Magnetic Shaker Bottle

Client Challenge:

A fitness founder had a patentable magnetic cap retention concept but lacked 3D CAD files, DFM engineering resources, and a qualified tooling partner.

Engineering Solution

Our engineering team created complete 3D CAD models, conducted mold flow analysis, generated 3D SLA functional mockups in 48 hours, and built precision S136 multi-cavity steel molds in 12 days.

Deliverables & Results

Golden samples approved on initial T1 trial run. Client successfully secured patent registration and scaled to 200,000 units within the first 12 months.

Project Procurement FAQ

Is a small trial order possible before larger quantities?

Yes. Existing molds: trial runs start at 500–1,000 pieces per color and design. Custom tooling: 10–20 off-tool T1 samples for physical validation before mass production approval.

Which files are needed for an accurate quotation?

3D CAD files (.STP, .STEP, .IGS), 2D drawings (.PDF, .DWG), or clear reference photos with dimensions and estimated quantity. DFM feedback is available within 24 hours.

How are proprietary designs and intellectual property protected?

A legally binding non-disclosure agreement (NDA) is signed before proprietary files are reviewed. Custom molds remain 100% customer-owned and are not shared or used for third-party orders.

Which food-contact test reports are available?

Reports from SGS, Intertek or TÜV cover requirements such as FDA 21 CFR (USA), LFGB (Germany), EU 10/2011 and California Proposition 65. Report scope is checked against the specific product and destination.

Is Amazon FBA labeling and individual packaging available?

Yes. Options include retail tuck boxes, FNSKU/UPC barcode stickers, warning polybags and ISTA-1A drop-tested shipping cartons for direct warehouse intake.
