Custom Injection Mold for Modular Long Tables — Product Introduction (Motek Furniture Mold Series)

Product Positioning

Motek offers customized injection mold solutions for modular, interlocking long plastic tables. Modular long tables are typically assembled from multiple tabletop modules or half-width panels joined through interlocking structures or hinges, balancing the needs of large-size use with the convenience of separate packaging and transport. The core challenges in mold development lie in shrinkage and warpage control of long large panels, dimensional interchangeability of interlocking/hinge areas, and appearance consistency across multiple modules. Motek focuses on mold flow pre-compensation, interlocking structure forming, and balanced ejection, helping customers achieve stable mass production of modular long table components with smooth assembly.

Core Specifications

Product Features

Shrinkage and Warpage Pre-Compensation for Long Panels.

Individual panels of modular long tables are large along the length direction, with significant deformation differences between long and short edges during shrinkage, prone to longitudinal bending or end warping. Motek evaluates long-edge versus short-edge shrinkage distribution through mold flow analysis, applies pre-deformation compensation to the cavity, and uses cooling channels zoned along the length direction to equalize cooling rates across panel regions. Industry experience shows that regular reinforcement rib design on the panel underside can effectively reduce deformation, but rib thickness must be controlled not to exceed panel wall thickness to avoid sink marks on the appearance surface.

Integral Forming and Interchangeability Control of Interlocking and Hinge Structures.

Modules of modular long tables are connected through snap-fits, interlocking slots, or hinge structures, with interlocking dimensional accuracy directly determining assembly smoothness and service stability. Motek forms edge snap-fits, connection points, and hinge mounting features through a slider system, with slider guidance and locking designs ensuring long-term positional accuracy. Cavity dimensions receive dedicated tolerance control at interlocking areas, ensuring uniform assembly gaps and stable interchangeability across different batches and cavity positions. For folding long tables using half-width hinge structures, the mold must coordinate with the forming solution for hinge mounting seats, ensuring the two half-width tabletops are coplanar and flat after hinge assembly.

Multi-Module Appearance Consistency Control.

Modular long tables are assembled from multiple modules, and the surface texture, gloss level, and color consistency of each module directly affect the finished product's visual quality. Motek applies consistency control to surface treatment across all cavity positions during cavity machining. Non-appearance areas can receive fine-texture or matte treatment as required, ensuring coordinated overall appearance after assembly.

Balanced Ejection to Protect Long Panel Appearance.

Long panels have large surfaces with relatively weak rigidity along the length direction, and uneven ejection force can cause stress whitening or bending deformation. Motek adopts a multi-point balanced ejector pin system arranged along both length and width directions, with ejection points preferentially located at reinforcement ribs, interlocking edges, and other non-appearance areas, ensuring panels do not deform during demolding with no visible ejector marks on the appearance surface.

Demolding Mechanism Optimized for Interlocking Undercuts.

Modular long table modules often feature snap-fits, slots, and other undercut structures. During demolding, sliders or inserts must first separate from the product before ejection. Motek adopts a slider and ejection linkage demolding solution: during mold opening, sliders and positioning inserts are first moved away to release the product from constraints, then the ejection action is performed, preventing the product from being damaged or deformed during demolding.
