Servo-Driven LSR Silicone Injection Molding Machine Closed-Loop Process Monitoring for Medical Audited Production

Servo-Driven LSR Silicone Injection Molding Machine with Closed-Loop Process Monitoring

When silicone parts go into medical devices, automotive assemblies or infant products, the question from the customer is not only whether the part is good today, but whether it was produced under recorded, repeatable conditions. This servo-driven LSR silicone injection molding machine answers that question: every shot is driven by closed-loop servo control and every parameter is logged, so production data can be retrieved for audits, traceability and continuous improvement.

The machine is specified around the customer product family, mould set and quality system, and can be delivered as a standalone unit or as part of a monitored production cell.

Technology Highlights

• Servo-driven hydraulics and metering: servo pumps deliver flow on demand instead of running continuously, which cuts electrical consumption and reduces oil heating in hot climates.
• Closed-loop process control: injection pressure, position and metering ratio are monitored and corrected in real time, holding part weight and dimension within a narrow band throughout the shift.
• Full parameter logging: shot profiles, cure times, mould temperatures, alarms and production counters are stored with time stamps and can be exported for quality records.
• Recipe and access management: mould recipes are locked by user level, so settings cannot be changed on the shop floor without authorisation.
• Statistical process monitoring: trend charts for key parameters and automatic warnings when values drift, allowing correction before a reject is produced.
• Remote diagnostics: the control system supports remote access, so our engineers can review alarms and parameters with your maintenance team without waiting for a site visit.
• Cold runner and precision metering: needle valve cold runner with servo-driven A and B dosing reduces scrap and keeps shot repeatability stable at low shot weights.

Typical Applications

• Medical and healthcare: catheter components, seals, membranes, infant care products and single-use device parts requiring documented production.
• Automotive: sealing rings, connector seals and gaskets supplied to OEM quality standards.
• Electronics: waterproof connectors, keypads and wearable components with tight dimensional requirements.
• Food contact and infant products: nipples, bottle parts, lids and tableware produced under food-grade documentation.
• Industrial silicone parts: bellows, rollers, vibration isolators and custom sealing profiles.

Advantages for Southeast Asian Manufacturers

• Lower energy bill: servo-driven systems consume power in proportion to actual work, which is a direct cost saving where industrial tariffs are high.
• Stable quality across shifts: closed-loop control removes operator-dependent variation between shifts and between machines.
• Audit-ready documentation: exported parameter and alarm records support ISO, medical and automotive customer audits.
• Faster troubleshooting: remote diagnostics and detailed alarm history shorten downtime, with spare parts stocked in Guangdong and fast air freight across the region.
• Climate-adapted hardware: cooling capacity, oil temperature management and cabinet ventilation are specified for tropical ambient conditions.
• Operator friendly: colour touch screen, mould recipe library and guided start-up reduce training time for new operators.

Configuration and Options

Standard scope includes the servo-driven LSR injection and clamping unit, servo metering package, cold runner set, water chiller, PLC with colour touch screen, data export and recipe management, tool kit and manual. Options include pigment metering, drum follower plate, robot interface, mould temperature controllers, additional data interface for MES integration and guarding to plant standard.

Frequently Asked Questions

Can production data be integrated with our system? Yes. Parameter and production records can be exported, and an MES interface is available as an option.

Is servo control worth it for small volumes? The energy saving is continuous, and the repeatability benefit is largest on multi-mould, high-mix production where settings change often.

What support is included? Installation, commissioning, operator training, remote diagnostics and a twelve-month warranty on the machine.
