What Specifications and Types of Disposable Syringe Molds Can We Produce?

As leading Chinese medical device mold manufacturers, we have accumulated over 40 years of experience in precision mold manufacturing since our establishment. We have consistently focused on the research, development, and manufacturing of disposable medical syringe mold systems. We don't just provide individual molds; instead, we offer clients comprehensive solutions for medical syringe molds that ensure stable and long-term mass production.

We understand that the core of medical syringe molds is not merely about the ability to 'make a mold,' but rather about achieving long-term stable mass production, consistent dimensional control, stable operation with high cavitation, and adherence to medical-grade precision and safety standards.

I. Range of Syringe Specifications We Can Manufacture

We are capable of producing disposable syringe molds that comply with international medical standards. Our comprehensive range of specifications includes molds for 0.3ml, 0.5ml, 1ml (specifically for vaccine/insulin applications), 2ml, 3ml (a globally common specification), 5ml, 10ml, 20ml, 30ml, 50ml, 100ml, 150ml, and 200ml syringes. Beyond standard sizes, we also offer specialized mold systems for feeder syringes, irrigator syringes, pre-filled syringes, veterinary syringes, and industrial syringes, including those for square syringe designs.

In terms of structural types, we provide molds for both two-part and three-part syringes. Our molds support various connection interfaces, such as Luer Slip (straight connection) and Luer Lock (threaded connection), as well as dual-use designs accommodating both straight and threaded connections. We tailor our solutions to meet the specific standards of our clients' target markets, including Asia, Europe, North America, the Middle East, and Africa.

II. Components of a Complete Syringe Mold System

Our approach extends beyond manufacturing individual molds; we deliver complete system solutions. These solutions encompass several critical mold components:

1. Barrel Molds

The barrel mold forms the core of the entire syringe system. Our technical capabilities for barrel molds include a wide range of cavitation options, from 8 to 96 cavities (8, 12, 16, 24, 32, 48, 64, 72, 96 cavities). We ensure compatibility with medical-grade high-transparency PP materials and achieve mirror polishing of the inner wall through high-grade precision machining. Our stringent processes maintain high-precision concentricity control, optimize gate design to prevent flow marks and weld lines, and utilize independent cooling systems to guarantee uniform wall thickness. With over 40 years of precision machining experience, we excel in stably controlling barrel transparency and weight consistency, validating our molds for long-term mass production environments, and supporting high-speed automatic assembly lines.

2. Plunger Molds

Plunger molds are particularly susceptible to deformation during high-speed mass production. To counteract this, our control focuses on anti-bending structural design, optimized cooling balance, high-speed ejection stability design, and multi-cavity synchronous consistency control. Our high-efficiency mass production molds typically range from 16 to 80 cavities and are designed to be adaptable to high-speed automatic assembly systems.

3. Piston Molds

The sealing performance of the piston directly impacts product safety. We meticulously control the precision of the sealing groove, the matching with the barrel's inner diameter, dimensional tolerance stability, and the long-term wear resistance of the mold. These measures collectively ensure reliable airtightness, smooth sliding, and stable long-term use of the syringe.

4. Needle Hub Molds

Our needle hub molds accommodate both Luer Slip (snap-fit) and Luer Lock precision threaded structures. Our technical advantages in this area include high-precision thread machining, the use of wear-resistant mold steel, meticulous thread consistency control, and designs compatible with automated assembly processes.

5. Cap / Protector Molds

These molds are designed for needle protection and sterile packaging systems. They feature high-speed production structures, automatic demolding designs, and multi-cavity mass production configurations.

III. Our Essential Difference from Ordinary Mold Factories

While many mold factories may claim they 
can 
“make” molds, what truly distinguishes us and determines long-term cooperation with medical clients are our advanced capabilities in several key areas:

• Long-term Mass Production Stability: We prioritize the stable performance of molds after 3-5 million cycles, rather than focusing solely on initial mold trial results. This long-term perspective is crucial for sustained medical device production.
• High Cavitation Operation Experience: Our extensive experience in mass producing high-cavitation syringe molds ensures consistent weight, uniform dimensions, and stable molding cycles across all cavities.
• Over 40 Years of Machining Experience Accumulation: Our four decades of accumulated expertise have allowed us to establish a stable machining system and mature process control procedures, which are fundamental to guaranteeing the highest levels of precision.
• Systemic Solution Capabilities: We offer comprehensive engineering support, including DFM (Design for Manufacturability) analysis, mold flow analysis, cooling system optimization, and automation matching design. This holistic approach ensures that our molds are integrated seamlessly into our clients' production lines.

IV. Application Areas

Our syringe molds are widely applied across various segments of the medical industry, supporting critical functions in:

• Vaccine production enterprises
• Insulin injection systems
• Hospital disposable medical consumables
• Medical OEM manufacturing plants
• Government medical supplies procurement projects
• International medical device export enterprises

We deeply understand and adhere to the stringent requirements for stability and reliability that are paramount in the medical industry.

V. We Focus More on Clients’ Long-term Success

In the medical industry, a mold represents not merely a purchase but a significant long-term investment. To support our clients' enduring success, we provide a robust framework of services:

• Standardized Mold Trial Procedures: Ensuring thorough testing and validation before deployment.
• Spare Parts Support System: Offering readily available components to minimize downtime.
• Maintenance Guidance Solutions: Providing expert advice and protocols for optimal mold upkeep.
• Long-term Cooperation Support: Building lasting partnerships based on continuous technical assistance and service.

With over 40 years of experience, we possess a profound understanding of how to:

• Proactively avoid potential hidden dangers that could emerge in later production stages.
• Effectively reduce long-term maintenance costs through superior design and material selection.
• Consistently ensure high-intensity continuous production capabilities for critical medical devices.
