Plastic Pen Barrel Injection Molding Machine：High-Precision, Efficient Pen Production

Introduction

 In competitive stationery manufacturing, the plastic pen barrel injection molding machine is a core asset determining product quality, 

efficiency, and profitability. Pen barrels require strict dimensional accuracy, smooth surfaces, and consistent thin walls – all dependent on 

specialized injection molding technology. Whether expanding a small factory or optimizing a large enterprise, this machine is critical for market 

competitiveness.

 Our machines are engineered exclusively for pen production, combining precision clamping, high-speed injection, and intelligent controls to deliver 

consistency, reduce waste, and shorten cycles. Below are key features, applications, and benefits to guide your decision.

Key Features

1. High-Precision Molding

Dimensional accuracy is non-negotiable for pen barrels. Our servo-driven clamping system (50–200 tons) ensures tight mold sealing, eliminating 

defects like flash and warping. The precision injection unit with a mixing screw uniformly melts PP, PS, ABS, PC, and recycled plastics. Adjustable 

injection speeds enable fine-tuning for different pen sizes, guaranteeing consistent wall thickness and perfect compatibility with refills.

2. Energy-Saving Servo Technology

Compared to traditional hydraulic machines, our servo-driven models cut energy consumption by 30–50%. The motor operates only during key

 processes, reducing electricity costs and noise (below 75dB) for an eco-friendly workshop.

3. Intuitive Operation

A user-friendly touchscreen stores up to 100 production recipes, enabling quick product changeovers in minutes. Real-time monitoring of critical 

parameters alerts operators to anomalies, minimizing defects. Minimal training is required for operation.

4. Custom Mold Compatibility

Our machines work seamlessly with custom molds for standard, ergonomic, or logo-embossed pen barrels. Adjustable mold mounting and ejection

 systems accommodate diverse designs, allowing product line diversification without extra equipment.

5. Durable & Low-Maintenance

Built with high-quality components (hardened steel screws, wear-resistant liners), the modular design simplifies maintenance. We offer a 1-year 

warranty and lifetime technical support for long-term reliability.

Application Scenarios

1. Large-Scale Production

High-tonnage models deliver continuous high-volume output for major stationery brands, meeting peak season demands. Energy efficiency and

 centralized monitoring optimize 24/7 operation.

2. Custom Promotional Pens

Mid-range models excel at small-batch, customized production (branded pens, souvenirs). Quick mold changeovers ensure precise logo placement 

and color consistency.

3. Eco-Friendly Manufacturing

Engineered for recycled plastics, our machines minimize defects and waste ( reducing costs and environmental impact for sustainable stationery brands.

4. Niche & High-End Pens

Low-tonnage models produce small batches of luxury, medical-grade, or ergonomic pens, with adjustable parameters ensuring flawless finishes and tight tolerances.

5. Small Factories & Startups

Entry-level models offer cost-effective solutions for local suppliers, with user-friendly controls and compact design fitting small workshops.
