Multi-Material Mastery: Integrating PPSU Bottles and Silicone Nipples in a Single Production Workflow

Modern infant feeding sets often combine different materials to optimize function and safety. Seamlessly integrating the production of PPSU bottles and silicone nipples presents unique logistical and technical challenges. This article explores how a unified workflow elegantly solves this integration puzzle.

A complete infant feeding set typically comprises a PPSU bottle and a silicone nipple. Each material—PPSU for its durability and sterilizability, and LSR for its softness and biocompatibility—requires distinct processing parameters and equipment. Traditionally, these components were produced on separate lines, complicating logistics and assembly. TYM's innovative approach integrates their production into a single, streamlined workflow.

The solution lies in a flexible, multi-process production cell. It features two dedicated stations: one for high-temperature PPSU injection molding and another for LSR molding. A central robotic transfer system intelligently moves molds and parts between these stations. The PPSU molding station handles the bottle preform, which is then transferred to a secondary station for final blowing or a take-out robot that places it directly into a waiting fixture.

Simultaneously, the LSR station molds the nipple. Once both components are produced, a final assembly robot picks and places the nipple onto the bottle, potentially incorporating an automatic leak-test station inline. This integrated cell is managed by a central controller that schedules production runs, tracks inventory of both materials, and ensures synchronization. This masterful orchestration reduces handling, minimizes the risk of contamination, and creates a highly efficient process for producing complete, ready-to-package feeding sets.
