In the manufacturing of medical consumables, a syringe may seem structurally simple, but it is composed of multiple plastic components that are precisely matched with each other. The needle holder and cylinder body not only need to meet strict requirements for size, concentricity, and assembly, but also need to maintain stability and consistency in high cavity count and short cycle continuous production. For manufacturing enterprises targeting large-scale markets, how to balance product quality, clean production, production capacity, and unit cost is the core issue in the injection molding process of medical consumables.
In this case, WINTEC e-winAll electric injection molding machineEfficiently and stably produce 128 chamber syringe needle holders and 48 chamber 10 ml Luer lock syringe barrels. With precision all electric drive, stable closed-loop control, equipment design for clean production, and inject AI digital solutions, the two applications demonstrate WINTEC's excellent molding capabilities and mature solutions for the medical industry.

Technical Parameters
Technical Parameters
128 cavities work simultaneously, and each cavity requires the same injection volume and molding conditions. A needle holder weighing 0.165 grams per piece, any slight deviation in one cavity will be amplified in bulk. E-win runs continuously in a cycle of 9 seconds to ensure that 128 cavities are consistent in each the first mock examination.

Technical Parameters
Technical Parameters
The cylinder body needs to be matched with components such as the piston and needle seat, and the cylinder diameter, concentricity, and interface size directly affect subsequent assembly. 48 cavitiesmoldEach mold weighs 220.8 grams and the products are transported downstream via a Z-shaped conveyor belt. Behind the 10 second cycle is continuous control over the consistency and long-term operational stability of each cavity.
The core challenge of high cavity count medical plastic parts
The needle hub and cylinder are typical high-precision medical plastic parts, and the main challenges faced during mass production are as follows:
●Dimensional accuracy and concentricity:Components such as the cylinder, piston, and needle seat require stable fit, and dimensional fluctuations may affect assembly, sealing, and performance, and even pose risks to patient health.
●Batch continuous production with high stability:Medical products are not allowed to be frequently adjusted, and fluctuations in weight and size between batches must be controlled.
●High cavity number charging balance:Each cavity must obtain consistent injection volume and molding conditions, and maintain repeatability in continuous production.
●Clean production:The design of equipment structure, lubrication, and moving parts should minimize the risk of particles and contamination, and adapt to the production environment of medical consumables.
●Cost control:High output means that every improvement in cycle time, energy consumption, material utilization, and yield rate will significantly affect the cost per unit.
How does the e-win all electric solution respond to these challenges
01more stable
E-win adopts dynamic and precise all electric drive, and stabilizes key process through closed-loop control. For multi cavity medical injection molded parts, precise injection execution helps control the injection volume each time and improve the consistency of each cavity product; Fully closed-loop control dynamically identifies and compensates for process fluctuations; The series of inject AI intelligent control modules configured in the two cases can further enhance the controllability of the melt state and forming process.
02Cleaner
Fully electric drive reduces the medium and heat load related to hydraulic systems, making it more suitable for injection molding applications in the medical industry that have high requirements for production environments. The e-win is equipped with contactless pull rods and linear guide structures, effectively reducing oil pollution and meeting clean production conditions from the perspective of equipment structure. The overall cleanliness performance of the machine has passed ISO 14644 testing, and the cleanroom level can reach ISO 7.
03more efficient
High cavity count and short cycle directly convert into considerable production capacity. The e-win 1800 runs a stable 128 cavity needle holder mold with a 9-second cycle; The e-win 3200 runs a 48 cavity cylindrical mold with a 10 second cycle and is connected downstream through a Z-shaped conveyor belt. The efficient injection unit, stable servo response, and automation coordination enable the equipment to maintain a competitive pace under large-scale production conditions.
04more economical
Medical consumables are a typical type of high-yield, cost driven application. All electric equipment drives various motion axes as needed, which helps to reduce non production energy consumption; Stable repeatability can reduce fluctuations, waste, and machine adjustment losses. The compact body, high cavity number molds, and automated conveying jointly enhance the output capacity per unit of land, helping manufacturing enterprises optimize single piece costs from multiple dimensions such as energy consumption, labor, quality, and overall equipment efficiency.
When the production scale is measured in millions of pieces, every improvement in stability - whether it is reducing one machine adjustment, lowering a batch of waste, or compressing one cycle - will be directly reflected in delivery capacity and production costs.
The competitiveness of medical plastic parts mass production comes from the precision and stability of each cycle, from a 0.165g needle holder to a 10ml Ruhr lock syringe barrel.
WINTEC e-win fully electric injection molding machines rely on ENGEL technology accumulation, precision servo control, and inject AI digital capabilities to provide injection molding solutions that balance precision, cleanliness, efficiency, and cost for the medical industry, helping customers establish stable and reliable large-scale production capabilities.
