Pet Product
DFM Engineering
Transform your silicone pet product concept into a manufacturable reality. Our engineers review every geometric, structural, and tooling detail before you commit to production.
Step 01 -- Design Evaluation
Rigorous evaluation of your source design files
We decode 3D models, 2D drawings, and reference samples to verify completeness, feasibility, and intent before engineering begins.
File Format & Integrity
We accept STEP, IGES, STL, SLDPRT, X_T, and PDF drawings. Each file is checked for closed surfaces, broken geometry, and version consistency.
Design Intent Clarification
Our team maps every feature against its functional purpose -- chewing resistance, grip, foldability, pet safety -- so no critical detail is lost in translation.
Material & Hardness Review
We validate your Shore A hardness, color pantones, FDA/LFGB requirements, and bonded material combinations (silicone + PP, TPE, metal).
Step 02 -- Manufacturability
Structural manufacturability analysis
Each geometric feature is scored against our 15-year production database for silicone pet products. We flag high-risk areas and propose engineered alternatives.
Flow & Fill Simulation
Predicts weld lines, trapped air, and short shots in complex pet toy geometries.
Feature Risk Scoring
Each boss, rib, hole, and radius is rated Green / Yellow / Red for production readiness.
Multi-Material Interface
Overmolding and bonding checks for silicone + PP, metal inserts, and textile anchors.
Pet-Safety Validation
Chew-force resistance, swallow-choke sizing, and sharp-edge elimination.
Step 03 -- Wall Thickness
Silicone wall thickness optimization
Wall thickness determines flow balance, cure time, demold success, and tactile feel. We benchmark your geometry against proven ranges and recommend precise adjustments.
Step 04 -- Draft & Parting
Demold strategy & parting line design
Silicone demolds very differently from rigid plastics. We define parting lines that preserve brand aesthetics while enabling safe, consistent ejection.
Draft Angle Strategy
Although silicone can tolerate near-zero draft, we add 0.5°-2° where ejection speed and surface finish demand it.
Parting Line Placement
Hidden along natural edges or decorative seams to minimize visible flash on finished pet products.
Ejection Mechanism
Stripper plates, air blow, or manual demold -- matched to product flexibility, surface finish, and cycle time.
Step 05 -- Risk Mapping
Undercuts & structural risk mapping
Undercuts are opportunities -- not failures -- when engineered right. We identify every risk area and prescribe a validated solution path.
Internal Undercuts
Deep internal grooves in slow-feeder mats or treat toys that cannot be reached by standard demold.
Thin Protrusions
Brush bristles, grip spikes, and texture nubs can tear during ejection if under-sized.
Snap-Fit Features
Lid closures, collapsible rims, and foldable hinges -- generally safe with correct wall transition.
Step 06 -- Tolerance
Tolerance & assembly analysis
Silicone shrinks between 1.8%-3.2% depending on hardness and geometry. We model shrinkage per feature, then stack-tolerance against mating parts.
General dimensional tolerance
±0.1 mmPrecision mold technology maintained across all pet product categories.
Shrinkage model
1.8-3.2%Material and hardness-specific shrinkage curves applied per feature zone.
Mating-part fit analysis
GD&TInterference, clearance, and transition fits mapped for silicone-to-PP, silicone-to-metal, and silicone-to-silicone assemblies.
Functional assembly test
VerifiedPull-force, snap-engagement, and seal-pressure validated on first-shot samples.
Step 07 -- Mold Engineering
Mold manufacturability review
A beautiful part is only as good as the tool that makes it. We co-engineer the mold concurrently with the product design.
Cavity Layout
- -- Single, multi-cavity, and family mold optimization based on EAU volume
- -- Balanced runner & gate placement for consistent fill
- -- Cold runner vs. cold-deck tooling trade-off analysis
Tooling Materials
- -- P20, NAK80, S136, 718H selection based on volume & finish
- -- Mirror polish / etch texture mapping to product aesthetics
- -- Lifetime expectancy: 300K - 1M+ shots
Cooling & Venting
- -- Conformal cooling paths for uniform cure
- -- Vent slot engineering to eliminate trapped-air burns
- -- Hot runner (LSR) or compression tooling as applicable
Cycle Time Modeling
- -- Cure time vs. wall thickness correlation
- -- Projected UPH (units per hour) for every cavity scenario
- -- Scrap-rate forecast tied to tooling investment
Step 08 -- Cost Engineering
Cost & mass production optimization
Great DFM pays for itself before the first shot. We quantify every design decision in time, dollars, and scrap percentage.
Material yield
Trim thick zones, redistribute mass, reduce silicone usage per unit without compromising feel.
Cycle time
Shorter cure cycles via wall balancing -- more units per press per shift.
Secondary processes
Consolidate silk-screen, UV coating, assembly steps where tooling can absorb them.
Packaging logistics
Collapsible, stackable, nestable form factors to lower freight & warehousing.
