24-Cavity Liquid Silicone Rubber Baby Nipple, 30-Second Fully Automated Production Solution

Precision. Speed. Zero Waste. One Complete Turnkey System.

The liquid silicone rubber (LSR) baby nipple market demands exceptional precision, consistent quality, and high-volume output. Traditional multi-step production processes struggle with gate marks, flash, manual handling, and long cycle times — all of which add cost and compromise quality.

Our 24-cavity LSR baby nipple production solution redefines efficiency. By integrating a 150-ton horizontal LSR injection molding machine with 24 needle-valve precision injection, a 24-cavity cold-runner mold, vacuum degassing, and robotic automation, we deliver a complete turnkey system that produces 24 flawless nipples every 30 seconds — fully automated, from raw material to finished product.

Core Technology Breakdown

150T Horizontal LSR Injection Molding Machine

Our 150-ton horizontal LSR injection molding machine is purpose-built for high-precision liquid silicone processing. Key specifications include:

- ▸ Clamping force: 150 tons — stable and rigid for 24-cavity molds
- ▸ LSR metering and mixing system with precision plunger injection unit
- ▸ Closed-loop servo control for consistent shot weight (±0.1%)
- ▸ Designed for 30-second cycle time at full 24-cavity production
- ▸ Integrated temperature control for both mold and injection unit

The machine delivers the steady clamping force and injection precision required for thin-wall, high-cavitation nipple molding.

24 Needle-Valve Precision Injection Control

Each of the 24 cavities is served by an individual needle-valve nozzle. This is critical for LSR nipple quality:

- - ▸ Independent open/close control per nozzle ensures balanced fill across all 24 cavities
  - ▸ Eliminates overfill or short-shot defects common in multi-cavity LSR molds
  - ▸ Precise timing control allows sequential or simultaneous injection profiles
  - ▸ Reduces material waste — no sprues or runners in the traditional sense

Result: Every nipple is identical in weight, geometry, and material properties—batch after batch.

24-Cavity Cold-Runner Mold with Vacuum Degassing

The cold-runner mold is the heart of the system. Our design features:

- ▸ 24-cavity cold-runner system — zero material waste, no runner recycling needed
  - ▸ Integrated vacuum pump for degassing during injection
  - ▸ Effectively removes trapped air and volatiles from the cavity
  - ▸ Eliminates air bubbles, voids, and surface defects
  - ▸ Gate vestige is minimized—no visible gate marks on the finished nipple
  - ▸ A proprietary cooling channel layout ensures uniform temperature across all 24 cavities

The vacuum-assisted molding process produces nipples with no gate marks and no flash—ready for packaging or downstream processing without secondary deflashing operations.

Robotic Arm — Full Automation

A dedicated robotic pick-and-place system completes the automation loop:

- ▸ Automatically extracts all 24 finished nipples simultaneously after mold opening
  - ▸ Places parts on conveyor or into organized trays for downstream inspection/packaging
  - ▸ Eliminates manual part removal — zero operator exposure to hot molds
  - ▸ Cycle-synchronized operation — no added cycle time for part extraction

With the robotic arm, the entire production cell runs with minimal human intervention, dramatically reducing labor costs and eliminating ergonomic risk.

Production Detail: A single operator can manage 3-4 production cells simultaneously, each producing ~92,000 nipples per day.

Frequently Asked Questions

Projects

Can this system handle different nipple sizes and designs?

Yes. The mold design can be customized for different nipple shapes, sizes, and hardness specifications. The machine’s injection parameters are fully programmable for quick changeovers between products. We recommend dedicated molds for each product for optimal cycle time and quality.

What is the typical ROI period?

Most customers achieve full ROI within 8–12 months, depending on production volume and local labor costs. The combination of 30-second cycle, 24-cavity output, and near-zero labor requirement delivers dramatic per-piece cost reduction compared to conventional silicone compression molding or low-cavitation injection.

What training and support do you provide?

We provide comprehensive on-site training for operators and maintenance technicians, complete documentation (machine manual, mold maintenance guide, process parameters), and remote technical support. Our engineers are available for on-site commissioning and troubleshooting worldwide.

Can existing molds be adapted to this machine?
