1.3: NDA and Confidentiality
If necessary, a Non-Disclosure Agreement (NDA) is signed before sharing customer designs or specifications.
Stage 2: Concept Design and Product Development
2.1: Conceptualization
Design engineers and product managers collaborate with the customer to develop initial concepts, including: Sketches and mood boards, Market research and competitor analysis, Functional requirements (e.g., suction function, ergonomic grip)
2.2: CAD Modeling
Designs are created in 3D CAD software (e.g., SolidWorks, AutoCAD, Rhino) with detailed dimensions and tolerances.
2.3: Design for Manufacturability (DFM)
Designs are reviewed for: Mold feasibility, Material flow and shrinkage, Demolding angles, Safety and ease of cleaning.
2.4: Customer Approval
The 3D design is sent to the customer for approval before prototyping begins. Feedback is incorporated until final confirmation.
2.5: Prototyping Options
Options include: 3D Printing (for visual and functional testing), Silicone Hand Molding (for material feel), Soft Tooling (low-cost aluminum molds).
2.6: Sample Review
Customers receive physical samples for: Material evaluation, Functional testing, Fit and finish, Color and branding review.
2.7: Sample Revisions
Multiple iterations may be conducted until the customer signs off on the Gold Sample or Production Sample.
Stage 3: Mold Design and Fabrication
3.1 Mold Design
Mold engineers create detailed mold blueprints based on final CAD files. Considerations include: Number of cavities, Cooling channels, Parting lines, Mold base compatibility.
3.2 CNC Machining
Molds are fabricated using CNC machining, EDM, and polishing. Materials used include: S136 stainless steel (for durability), Aluminum (for temporary molds).
3.3 Mold Testing (T0, T1 trials)
Initial mold trials are conducted to evaluate: Filling behavior, Air traps, Flash occurrence, Dimensional accuracy, Corrections are made before moving to mass production.
Stage 4: Raw Material Procurement and Handling
4.1 Material Selection
Only FDA and LFGB certified food-grade silicone is used. Properties include: BPA-free, Non-toxic, Heat and cold resistance (-40℃ to 230℃), Soft, flexible, yet durable.
4.2 Supplier Evaluation
Suppliers are vetted for: Quality certifications (ISO, FDA, LFGB), Traceability, Batch consistency.
4.3 Material Storage
Materials are stored in a temperature- and humidity-controlled environment, away from dust, UV exposure, and contaminants.
Stage 5: Silicone Compounding and Color Matching
5.1 Color Matching
Color masterbatch is created using silicone pigments. Color matching is based on Pantone references or customer swatches.
5.2 Compounding
Silicone base, pigments, and additives (if any) are blended using a two-roll mill or kneader.
5.3 Storage and Labeling
Each batch is labeled with: Batch number, Color code, Production date, Operator ID.
Stage 6: Molding Process
6.1 Compression Molding
Most silicone baby products are made using compression molding: Silicone compound is placed into the mold cavity. The mold is closed under high pressure and heated (170 ℃
– 200 ℃). Curing time ranges from 30 seconds to 5 minutes, depending on thickness.
6.2 Injection Molding (for complex items)
Injection molding is used for high-volume or complex designs. Liquid Silicone Rubber (LSR) is injected into the mold. Offers better precision and faster cycles.
6.3 Demolding
After curing, parts are demolded manually or with automated ejectors.
Stage 7: Post-Molding Processing
7.1 Trimming
Excess flash and sprues are removed using: Scissors or blades, Cryogenic deflashing (optional).
7.2 Surface Finishing
Surface may be: Polished, Sandblasted, Matte or glossy finished based on mold texture.
Stage 8: Printing and Decoration
8.1 Printing Options
Pad Printing: For logos, characters, or measurements, Screen Printing: For large surface design, Laser Etching: Permanent markings, Embossing/Debossing: Molded directly into product.
8.2 Ink and Adhesion
Only food-safe, solvent-free inks are used. Adhesion tests (tape test, rub test) are conducted.
Stage 9: Quality Control and Inspection
9.1 In-Process QC
QC personnel inspect during molding and post-processing for: Flash, Deformation, Color inconsistency, Surface defects.
9.2 Final QC
Final inspection includes:, Dimensional check (calipers, gauges), Functionality (e.g., suction strength, stacking), Smell test (to detect off-gassing), Drop and durability test.
