High-voltage DC relays are indispensable core components widely used in new energy vehicles, battery energy storage systems, solar photovoltaic stations, and industrial high-voltage control cabinets. Vacuum exhausting, inert gas filling, pressure holding, and pipeline cutting are core precision procedures of high voltage relay encapsulation. These processes directly determine the airtight stability, insulation performance, service life and operational safety of high-voltage relays. Any inaccuracy in high voltage relay gas filling and pipe cutting will cause internal arcing, gas leakage and premature relay failure, seriously affecting the stability of the entire electrical control system.

Most traditional relay manufacturing factories still rely on single-station semi-automatic devices or manual operation for high voltage relay gas treatment and pipeline processing. Outdated production methods bring widespread industry pain points: low production efficiency, unstable vacuum and gas filling precision, irregular relay pipe cutting dimensions, and high product defect rates. Unstable batch quality leads to increased labor costs and material waste, failing to meet the strict quality and mass production standards of global new energy and high-end industrial supply chains.

With over 13 years of professional experience in precision testing and automation equipment R&D and manufacturing, HCTE independently developed the 12-station automated high voltage relay gas filling, exhausting and pipe cutting equipment. As a high-tech enterprise certified with ISO and CE standards, HCTE focuses on high-precision industrial automation solutions for new energy component manufacturing. This all-in-one relay encapsulation machine integrates vacuum exhausting, precise inert gas injection, constant-pressure leakage testing, fixed-length pipe cutting and cyclic loading and unloading, supporting high-precision, zero-difference and high-volume mass production for high-voltage relay post-processing.

Different from traditional single-station relay gas filling and cutting equipment that can only execute one single process at a time with long idle waiting time, HCTE’s exclusive rotary platform adopts a 12-independent-station cyclic design tailored for high voltage relay processing. Each station independently completes full-process operations including workpiece loading, high-vacuum exhausting, precise inert gas filling, constant-pressure holding leakage detection, precision pipe cutting and finished product unloading without mutual interference.

The entire equipment supports 24-hour uninterrupted continuous operation, achieving fully automated streamlined relay encapsulation. This optimized structural design maximizes production beat utilization, greatly shortens single-piece processing cycles and significantly improves daily production output. It perfectly adapts to large-scale batch production demands of modern high-voltage relay factories, thoroughly solving the capacity bottleneck of traditional relay processing equipment.

Internal gas purity and cavity tightness are the core criteria for evaluating high-voltage relay quality. Insufficient vacuum exhausting and uneven gas filling easily cause internal oxidation, arc discharge and long-term gas leakage failure of relays. This professional high voltage relay gas filling machine is equipped with imported high-precision pressure sensors and intelligent constant-flow control modules, supporting flexible and precise adjustment of vacuum degree, filling pressure, gas flow rate and pressure holding time to match different relay model specifications and production standards.

Adopting HCTE’s exclusive post-pressure-stabilization cutting process, the equipment only performs automatic pipe cutting after the relay cavity pressure and gas purity reach stable qualified standards. This standardized processing method completely eliminates quality risks such as residual air, impure inert gas and insufficient sealing caused by manual operation. It stably guarantees consistent relay airtight performance in mass production and effectively reduces product rework and scrap rates for relay manufacturing lines.

Manual cutting and ordinary pneumatic cutting tools cannot ensure machining accuracy, often resulting in uneven cutting notches, inconsistent reserved pipeline lengths and burr defects. These common problems in traditional relay pipe cutting processes lead to poor assembly matching, increased assembly difficulty and frequent secondary rework, seriously restricting production efficiency and product yield.

Equipped with a self-developed high-rigidity mechanical precision cutting mechanism, HCTE’s relay pipe cutting equipment delivers ultra-high positioning accuracy and stable cutting strokes. All relay pipelines achieve flat, burr-free cuts and unified fixed-length dimensions in batch production. The standardized precision cutting process optimizes subsequent assembly procedures, greatly improves overall production yield and realizes unified high-quality standards for large-scale high-voltage relay manufacturing.

The equipment is equipped with an industrial-grade visual HMI human-machine interaction system, realizing real-time dynamic monitoring of station operating status, process parameter data, production output and equipment fault information. The intuitive and simple operation interface lowers operator learning thresholds and effectively avoids human misoperation during high voltage relay gas filling and cutting procedures.

It supports one-key storage, calling and switching of multiple customized process recipes. Manufacturers can directly call preset parameters for different high-voltage relay models without repeated debugging and calibration, greatly shortening model switching time and improving production flexibility. Equipped with a sound-light integrated alarm system, the equipment can timely feed back abnormal faults, helping technical teams quickly troubleshoot problems and reduce production line downtime losses for relay encapsulation production.

Tailored for long-term continuous industrial production scenarios, this automated relay encapsulation machine adopts a full-range safety light curtain protection system. It triggers an immediate emergency stop once personnel or foreign objects enter the working area, ensuring 100% on-site operation safety. The fully closed dust-proof and anti-corrosion cabinet structure features stable mechanical performance and ultra-low failure rate, adapting to harsh workshop environments for long-term continuous high voltage relay processing.

Matched with adjustable support feet and heavy-duty mobile casters, the equipment supports flexible workshop layout adjustment and convenient daily maintenance. Strictly manufactured in accordance with HCTE’s ISO9001 quality management system, the equipment achieves a one-time inspection pass rate of over 99.7%, ensuring stable 24-hour continuous operation, reducing post-maintenance costs and improving production continuity for high-volume relay production.

HCTE’s automated relay gas treatment and pipe cutting equipment is professionally customized for high-precision encapsulation of high-voltage DC relays. It is widely applicable to vacuum exhausting, inert gas filling, airtight leakage detection and fixed-length pipe cutting processes for new energy vehicle high-voltage relays, energy storage system high-power relays, photovoltaic power generation relays and industrial DC high-voltage relays. As professional relay vacuum gas filling equipment, it is core automation equipment for upgrading quality and efficiency in relay post-encapsulation processes.

Replacing traditional manual and semi-automatic production processes, this automated solution helps relay manufacturing enterprises realize standardized, intelligent and efficient production. With mature overseas project experience covering Europe, Asia, Africa and other regions, HCTE assists global new energy component manufacturers in improving product competitiveness in the international market.

With the continuous upgrading of global new energy industry standards, high-voltage relays have put forward higher requirements for airtight stability, batch consistency and service life. Traditional manual and semi-automated production processes can no longer meet the high-end procurement standards of global new energy and industrial brands.
