Motek introduces dedicated injection molds for turnover boxes used exclusively within light industry factories producing apparel, footwear, and headwear. Unlike logistics crates for external distribution, these factory-internal containers are designed for in-plant material handling, work-in-progress (WIP) transfer between production stations, component sorting, and finished goods staging—prioritizing lightweight handling, stackability, cleanliness, and compatibility with factory shelving and conveyor systems. The core challenges in mold development lie in clean, dust-free surface quality for fabric and footwear components, structural strength for repeated in-plant handling, and efficient stackability for space-constrained production floors. Motek addresses these through cavity surface treatment, structural reinforcement, and stacking feature design, helping customers achieve stable mass production of factory-internal turnover boxes.

Clean, Dust-Free Surface Quality for Fabric and Footwear Components.
Apparel, footwear, and headwear components are sensitive to dust, snags, and surface contamination. Motek polishes cavity interior surfaces to a smooth finish, eliminating burrs, sharp edges, and rough textures that could snag fabrics or trap dust. All corners and rib roots are rounded to protect delicate materials. Where required, antistatic material grades can be specified to prevent dust attraction.
Structural Strength for Repeated In-Plant Handling.
Factory-internal turnover boxes are handled continuously throughout the production day. Motek reinforces corner posts, base runners, and side wall ribs through optimized wall thickness and rib layout, ensuring the box maintains rigidity under repeated loading, stacking, and handling. Mold flow analysis verifies filling completeness at corner nodes where wall sections converge.
Efficient Stackability for Space-Constrained Production Floors.
Production floors have limited space, and turnover boxes must stack compactly and stably. Motek forms stacking shoulders and nesting features with tight tolerance control, ensuring secure vertical stacking and compact nesting when empty. Stacking shoulder dimensions are verified for compatibility with factory shelving, conveyor systems, and standard pallets.
Ventilation and Visibility Design.
While factory-internal boxes prioritize cleanliness over ventilation, some apparel and footwear applications benefit from airflow to prevent moisture buildup. Motek forms ventilation slots or perforations where required, with clean edges and no sharp burrs. Where visual identification of contents is needed, transparent or semi-transparent material grades can be accommodated with optical-grade cavity polishing.
Compatibility with Factory Handling Systems.
Turnover boxes must interface smoothly with factory shelving, conveyor belts, and manual handling equipment. Motek verifies base dimensions, stacking shoulder geometry, and handle positions for compatibility with standard factory handling systems during the design phase.
Lightweight Design for Manual Handling.
Factory workers frequently lift and move turnover boxes during production. Motek optimizes wall thickness distribution to minimize weight while maintaining structural strength, reducing worker fatigue and improving handling efficiency.
Motek light industry apparel, footwear & headwear factory-dedicated turnover box molds are suitable for:
After the customer provides 3D product drawings, load-bearing requirements, cleanliness specifications, and handling system compatibility requirements, Motek completes mold flow analysis (including structural reinforcement evaluation, stacking feature verification, and surface quality assessment) and mold structure confirmation; cavity steel and hot runner systems are procured according to agreed specifications; progress and key milestones are regularly reported during processing. During trial molding, emphasis is placed on verifying surface cleanliness, structural strength, stacking stability, and handling system compatibility, with samples and inspection reports provided. Before shipment, molds undergo anti-rust treatment and action testing, with water circuit diagrams, consumable parts lists, and maintenance instructions provided. Technical support is available during the warranty period, with lifetime maintenance consultation.
