Quality Assurance
We enforce a rigorous QA regimen aligned with ISO 9001 and food-contact regulations. Incoming LSR batches are validated via FTIR and material certificates; parts undergo dimensional CMM inspection, Shore A hardness testing, and automated visual checks. Functional tests include cracking-pressure rigs, leak and backflow tests, cycle-life endurance (up to 500k actuations), and accelerated aging to verify performance with acidic and oily condiments. Migration and extractables testing (EU 10/2011 / FDA guidance) and ultrasonic cleaning validation ensure safe, compliant parts ready for food contact. Full batch traceability and FAI documentation accompany deliveries.
Why Choose Us?
- Condiment-Specific Design Expertise — We tune slit geometry, durometer, and cracking pressure to deliver consistent dispense rates and prevent clogging or stringing for thick sauces.
- End-to-End OEM Support — DFM, rapid prototyping, tooling, color matching, laser/ink marking, and custom packaging — all managed under one roof.
- Scalable, High-Quality Production — Clean LSR injection lines with automated dosing, post-cure ovens, and tight SPC controls for repeatable, high-yield manufacturing.
- Regulatory & Food-Safety Focus — Manufacturing and testing protocols designed specifically to meet FDA/LFGB food contact requirements and retailer specifications.
Factory Overview
Our manufacturing campus integrates advanced mold making (5-axis CNC, mirror EDM, slow wire-cutting) with dedicated LSR injection presses and automated dosing/curing systems to guarantee consistent chemistry and part geometry. Post-mold operations include precision trimming, ultrasonic cleaning, laser/ink marking, and sealed packaging lines. In-house labs perform cracking-pressure testing rigs, CMM inspections, tensile/durometer testing, and migration analysis. With ISO 9001 systems and flexible tooling capacity, we support rapid sampling through high-volume production with reliable lead times and strict food-contact traceability.
