Physical fitness is a critical requirement. Operators must have normal eyesight, including corrected vision, to monitor material feeding, forming processes, and product quality in real time. They need intact hand-eye coordination to handle control panels, material adjustments, and emergency operations accurately.
Personnel must be in good physical health with no chronic diseases, vertigo, or hearing impairments that could affect their ability to respond to machine signals and emergency situations. The working environment involves moderate noise and continuous standing, so physical endurance is necessary for sustained daily operation.
Entry-level operators without prior experience must complete a minimum of 30 hours of systematic on-the-job training, including theoretical learning and practical operation. Experienced personnel with more than 6 months of semi-automatic thermoforming equipment operation experience can be assigned to independent posts after a 10-hour adaptation training specific to the machine model.
All operators must master core skills including equipment parameter setting, plastic sheet loading and positioning, vacuum forming process monitoring, preliminary product quality inspection, and routine machine maintenance. These skills directly determine production efficiency and finished product qualification rate.
Qualified operators can identify common forming defects such as insufficient forming, material wrinkling, and overheating damage, and make independent adjustments to parameters like heating temperature, holding time, and vacuum pressure to resolve minor issues within 5 minutes.
Formal pre-job training and certification are mandatory for all personnel operating a Semi Automatic Vacuum Forming Machine. Untrained operators are prohibited from independent operation to avoid equipment damage, production accidents, and quality non-compliance.
Theoretical training covers four core modules, each requiring a passing score of 85 or higher in the assessment. The modules include machine structure and working principle, safety operation specifications, parameter setting standards, and daily maintenance knowledge.
Practical training accounts for 70% of the total training duration, focusing on hands-on operation proficiency. Trainees practice under the guidance of certified instructors until they can complete the entire production process independently.
After completing training, personnel must pass a unified assessment including theoretical written examination and practical operation evaluation. Those who pass both parts receive an official operation certification and are allowed to work independently.
Certification is valid for 2 years. Operators must participate in retraining and reassessment before expiration to update their knowledge of upgraded functions, new materials, and optimized operation methods. Expired certifications without renewal will result in suspension of independent operation rights.
Operators of a Semi Automatic Vacuum Forming Machine undertake clear daily responsibilities covering pre-production preparation, in-production monitoring, post-production finishing, and teamwork coordination. Each duty directly affects the overall production efficiency.
Before starting the machine, operators complete a full set of inspection tasks within 15 minutes to ensure the equipment is in optimal working condition. This step reduces downtime caused by equipment abnormalities during production.

During continuous operation, operators remain at their posts and monitor the machine status in real time. They are not allowed to leave the equipment without permission or perform unrelated operations during working hours.
Conduct sampling inspection on finished products every 10 pieces, checking dimensions, surface smoothness, forming completeness, and defects. Adjust parameters immediately if non-conforming products are found to reduce scrap rate to below 3%.
Record key production data including total output, qualified product quantity, abnormal situations, and parameter adjustments. Timely report equipment failures or unresolved quality issues to maintenance personnel and supervisors to avoid prolonged downtime.
Follow safety protocols strictly during operation, including using protective equipment, avoiding direct contact with heating components, and operating control buttons according to standard procedures to prevent personal injury.
After completing production tasks, shut down the machine following the correct sequence: stop heating system → turn off vacuum pump → cut off power → close air supply. Never cut off power directly to avoid equipment damage.
Clean the workbench, forming mold, and heating components, removing plastic residues and dust. Use designated cleaning tools to avoid scratching mold surfaces or damaging electrical parts.
Sort and count finished products, separate qualified and defective items, and attach production labels. Organize production logs and submit them to the management team as required.
Perform routine maintenance including lubricating movable parts, checking pipeline connections, and covering the machine with a dust cover if it will be idle for a long time.
Safety is the top priority in operating a Semi Automatic Vacuum Forming Machine. All personnel must comply with strict safety requirements to protect personal safety, extend equipment service life, and ensure stable production.
Operators must wear standard personal protective equipment during the entire working period. Non-compliance with PPE usage is a serious violation of operation rules.
Operators must not modify the machine's safety protection devices, including emergency stop buttons, safety interlocks, and temperature overload protectors. Any damage to safety components requires immediate reporting and shutdown for maintenance.
The emergency stop button can only be used in critical situations such as equipment malfunction, material jamming, or personal safety risks. After using the emergency stop, conduct a full equipment inspection before restarting.
Do not place hands, tools, or foreign objects near the mold area during the heating and forming process. Wait for the system to stop completely and cool down before performing mold replacement or cleaning.
Regularly check for overheating, abnormal noise, or air leakage during operation. If any abnormality is detected, shut down the machine immediately and notify maintenance personnel instead of continuing operation.
The operating area must maintain good ventilation and lighting conditions, with illumination intensity not less than 300 lux to ensure clear observation of the forming process.
Flammable and explosive materials are strictly prohibited within 1 meter of the machine. Fire extinguishers must be equipped in the working area and checked monthly for availability.
Keep the workplace tidy, with raw materials, finished products, and tools placed in designated areas. Do not stack items randomly to avoid blocking emergency passages.
Operators share responsibility for daily maintenance and inspection of the Semi Automatic Vacuum Forming Machine. Professional maintenance personnel handle major overhauls, while operators complete routine checks to keep the equipment in good condition.
Daily maintenance is a core responsibility, taking 20-30 minutes after each production shift. Consistent maintenance extends the machine's service life by 3-5 years and reduces failure rates significantly.
