Many experienced workers in mold manufacturing facilities mistakenly believe that hanging a television screen to display drawings constitutes digitalization. The core issue lies here: while screens are installed, version control still relies on USB drives, and line changeovers require technicians to run to the shop floor to adjust machines. Engineers waste their time searching for files and modifying parameters. For engineers in mold factories, the first step of digitalization is not purchasing screens, but rather managing work instructions at the workstation and controlling the rhythm of line changeovers.
1. Do Not Rely on Memory for Drawing Versions; Let the System Lock Them
Mold parts differ from electronic components. If a single mold frame undergoes changes such as replacing inserts or switching steel grades, the work instructions must be updated accordingly. In the past, process engineers would modify documents and send them to group chats, after which team leaders printed them out and placed them in workstation folders, leaving old versions lying in drawers. Suppose a hypothetical precision stamping mold factory changes molds three times a day. Before each changeover, an engineer spends over ten minutes verifying drawing versions. In the event of urgent orders, incorrect versions are easily selected. Engineers no longer need to act as human version controllers; this is the most practical step in digitalizing engineers in mold factories.
2. Spend Line Changeover Adjustment Time on Parameter Verification
What do mold factories fear most during line changeovers? It is not the slowness of removing and installing molds, but discovering mismatched parameters when testing the first piece after installation. The clamping force, holding time, and material temperature specified in the work instruction may differ slightly from the actual settings on the machine, resulting in a scrapped first piece. Consider this scenario: on a production line making connector molds, an engineer holds a paper SOP and verifies machine parameters item by item after a changeover. Estimating based on the plan, a single verification takes seven to eight minutes. With five changeovers a day, half an hour is wasted purely on walking. By mounting an ESOP terminal all-in-one unit beside the machine, the relevant work instruction and checklist for the specific mold can be pulled up directly on the screen during changeovers. Parameters should be designed as check-box confirmations, and the changeover is only considered complete after the engineer signs off. A practical insight is to avoid listing too many inspection items; include only the five to eight items that truly affect the first piece quality. Listing twenty items will result in no one taking them seriously. The value of digitalizing engineers in mold factories is reflected in these changeover actions.
3. Do Not Rely on Word-of-Mouth for Training and Newcomer Onboarding
Technician turnover in mold factories is significant. New adjustment apprentices often go on duty after watching their mentors for two weeks, simply copying what the mentor does and omitting steps the mentor missed. ESOP systems with training modules allow work instructions to be accompanied by operation videos and assessment items. Newcomers watch the content on their mobile devices before operating the machine. Suppose a hypothetical mold factory with twenty injection molding machines follows this plan. The estimated cycle for a newcomer to operate independently can be reduced from four weeks to approximately two and a half weeks. This assumes that veteran workers record the videos and SOPs themselves rather than hiring external personnel, as they speak the language recognized on the shop floor.
4. All-in-One Units Must Be Suitable for Self-Production; This Is Critical in Mold Workshops
Mold workshops have heavy oil and grease, and high temperatures in summer. Ordinary commercial screens often develop dead pixels within six months. When selecting terminals, engineers should note two points: first, do not install the screen directly facing the machine nozzle, as hot air blowing directly onto the screen causes issues; second, route cables through open cable trays. Frequent movement of mold frames in the workshop means hidden cables are easily crushed and broken. These are experiences accumulated from installing dozens of terminals, not information found in manuals.
To conclude, digitalization for engineers in mold factories does not require a large-scale rollout immediately. Start by creating a pilot station with frequent line changeovers: put SOPs on screens, digitize checklists, and lock versions. After running smoothly for a month, expand to other machines. When selecting equipment, clarify whether it is from the original manufacturer and if future upgrades incur fees. These two points are more effective than a feature list. If unsure about how to implement this in your own workshop, discussing site cabling with technical staff is more practical than reviewing ten proposals.
