2. Core Factors Determining Minimum Workshop Size for PET Sauce Bottle Production

2.1 Equipment Structure and Operational Spacing Requirements

The overall dimension and operational stroke of PET blow molding equipment are the core factors determining the minimum workshop area. Different from water and beverage thin-walled PET bottle production lines, sauce bottle blow molding equipment needs to match thick-wall bottle molding, high-pressure blowing and stable cooling shaping functions, with slightly larger equipment body size and mold opening stroke. Yuda professional PET sauce bottle blow molding machine adopts optimized compact fuselage design, integrating heating oven, blowing platform, hydraulic system and control system, avoiding the scattered layout and large space occupation of traditional split equipment.

In actual production, the equipment cannot be placed closely against the wall or without reserved spacing. It is necessary to reserve fixed operational spacing for mold replacement, equipment maintenance, daily debugging and fault inspection. Meanwhile, the bottle embryo feeding and finished product discharging directions require smooth passage space. The minimum single equipment operation spacing includes front and rear operational maintenance space and left and right material handling space, which directly determines the basic length and width of the workshop.

2.2 Production Line Automation Configuration Differences

The minimum workshop size varies significantly according to different automation levels of PET sauce bottle production lines, including semi-automatic production configuration, standard full-automatic single-line configuration and multi-line parallel mass production configuration. Semi-automatic production lines require manual embryo placing and finished product picking, needing reserved manual operation channels and station space; full-automatic lines adopt automatic embryo feeding, automatic blowing and automatic discharging, saving manual operation space but needing reserved space for supporting conveying equipment.

Yuda’s semi-automatic PET sauce bottle blow molding machine is suitable for small-batch and flexible production, with compact equipment layout and low space demand. The full-automatic intelligent production line realizes unmanned continuous production, with orderly supporting equipment layout and standardized space occupation. Enterprises can select matching workshop size standards according to their daily output demands and automation investment budgets.

2.3 Functional Supporting Zone Space Demand

A complete PET sauce bottle blow molding production workshop is not only equipped with main molding equipment area, but also needs to divide independent functional areas including raw material storage area, bottle embryo temporary storage area, finished product inspection and storage area, equipment maintenance area and passage area. As food-grade packaging container production, the workshop also needs reserved space for simple dust-proof and constant-temperature auxiliary facilities to ensure food production safety standards.

The raw material area is used for stacking PET raw material particles and color masterbatch, needing dry and independent small space; the bottle embryo temporary storage area is specially placed for pre-injected PET sauce bottle embryos, avoiding mixed placement with finished products; the finished product area is used for temporary storage and manual inspection of blown qualified sauce bottles. All functional areas need standardized minimum spacing division, which is an indispensable part of the minimum workshop size calculation.

2.4 Safety Production and Environmental Compliance Standards

PET blow molding production belongs to thermoplastic processing production, involving electrical equipment operation, high-temperature heating and hydraulic transmission systems, which must comply with industrial workshop safety production specifications. The workshop needs to reserve fire passage spacing, equipment heat dissipation space and electrical safety isolation space. Too narrow space will cause poor equipment heat dissipation, increased equipment failure rate and hidden fire hazards.

In addition, food-grade sauce bottle packaging production has environmental requirements for workshop cleanliness and ventilation. The minimum workshop size must meet the ventilation and dust removal layout space, ensuring that the production environment meets food packaging product production standards and avoids product contamination affecting food safety certification.
