INNOPKG Customer Success Story: GLOW LAB
I. Executive Summary: The Quantifiable Leap from Efficiency Bottleneck to Production Excellence
Overview
This case study details the critical production challenges faced by GLOW LAB, the natural/science-backed skincare brand under the Earthwise Group in New Zealand, specifically concerning their high-value personal care product lines. GLOW LAB was severely constrained by their existing equipment’s inadequate cap handling precision and low efficiency (below $50 \text{ bpm}$), particularly regarding the torque consistency of complex pump caps and standard round caps.
Solution
INNOPKG successfully addressed this challenge by deploying its flagship Pallas 310 High-Precision Servo Capping System. The Pallas 310 delivered ultra-high repeatability and accuracy, powered by its European-brand motion controller, servo-driven capping heads, and custom silicone-lined gripping jaws.
Core Quantifiable Outcomes
Following $30 \text{ days}$ of system integration and optimization, the Pallas 310 achieved the following key quantifiable results for GLOW LAB:
- Production Efficiency Increase: The actual line speed was raised from $48 \text{ bpm}$ to a stable $78 \text{ bpm}$, representing an increase of $\mathbf{62.5\%}$.
- Effective Production Rate: The guaranteed $98\%$ minimum effective production rate was validated over $90 \text{ continuous days}$ of operation, resulting in an $85\%$ reduction in unscheduled downtime at the capping station.
- Product Rejection Rate Reduction (Cap Damage Rate): Due to precise servo torque control, the product rejection rate caused by improper capping decreased from $0.8\%$ to less than $0.05\%$, saving GLOW LAB over $\mathbf{NZD} 45,000 \text{ annually}$ in material losses.
The Pallas 310 not only resolved GLOW LAB’s immediate production challenges but also provided a solid, quantifiable technological foundation for future market expansion.
II. The Challenge: High-Value Products Constrained by Low-Efficiency Equipment
A. Client Background and Product Positioning
GLOW LAB is a skincare brand emphasizing the combination of natural ingredients with scientific efficacy, operating under the Earthwise Group. Their products (such as creams, serums, and body lotions) are positioned as mid-to-high-end consumer goods, requiring extremely high standards for visual integrity and seal reliability of the packaging. GLOW LAB’s packaging strategy is diverse, utilizing round containers with both standard round caps and complex pump caps.
B. Analysis of Existing Production Bottlenecks
GLOW LAB’s existing, older capping machine (non-servo-driven) posed significant operational risks across the following three key areas:
1. Speed and Throughput Limitation (Capacity Limitation)
The old equipment, which used a mechanical capping method, had a maximum stable speed of only $50 \text{ bpm}$. This severely constrained the capacity of their advanced fillers (which could reach $100 \text{ bpm}$), making the capping station the sole bottleneck of the entire line. During peak demand periods, GLOW LAB incurred high overtime costs and third-party packaging service fees to meet market supply.
2. Capping Precision and Torque Inconsistency
Given that GLOW LAB products contain natural oils and active ingredients, the sealing integrity is paramount. The inconsistent torque of the old equipment led to:
- Overtightening: Stripping the plastic threads of the pump cap, affecting aesthetics, and making it difficult for consumers to open.
- Undertightening: Posing a leakage risk, especially during long-haul shipping to international markets, severely damaging brand reputation.The product rejection rate stood at $0.8\%$, primarily due to damaged caps or poor sealing, resulting in unnecessary material waste.
3. Poor Adaptability to Complex Cap Types
GLOW LAB needed to handle caps ranging from $15 \text{ mm}$ to $60 \text{ mm}$ in diameter, especially Pump Caps, which require precise pick-and-place and orientation. The old equipment had a high error rate in positioning and grasping pump caps, leading to frequent line stops and manual intervention, which drastically reduced the actual effective production rate.
III. The INNOPKG Solution: Pallas 310 Servo Capping System Deployment
A. Customized System Configuration
INNOPKG engineers collaborated closely with the GLOW LAB team to deploy a three-head configuration of the Pallas 310 High-Precision Servo Capping System (to meet the required maximum speed of $80 \text{ bpm}$), integrating an automatic cap sorter and feeder system.
1. Core Technology: European Motion Control and Servo Drive
The Pallas 310 eschewed the mechanical cam or friction wheel drives of GLOW LAB’s old equipment in favor of:
- European-Brand Motion Controller: Ensures microsecond-level synchronous control over all motion axes, achieving accurate cap pick-and-place and positioning.
- Servo Capping System: Each capping head is driven by an independent servo motor, allows operators to precisely set the digital torque value and rotation angle via the Human-Machine Interface (HMI). This enabled GLOW LAB to establish unique, repeatable, and verifiable capping programs for different cap types, switchable with a single touch.
2. Cap Protection and Gripping Innovation
To meet the aesthetic demands of GLOW LAB’s high-value products, the Pallas 310 incorporates silicon-lined gripping jaws.
- Anti-Slip: The silicone lining provides high friction, preventing cap slippage even at the high speed of $78 \text{ bpm}$.
- Anti-Wear: The soft silicone surface prevents any scratches or indentations on the cap surface, ensuring the product’s flawless presentation on the retail shelf.
