Household Hamburger Backrest Stool Mold — Product Introduction (Motek Furniture Mold Series)

Product Positioning

Motek introduces dedicated injection mold solutions for household hamburger backrest stools. The "hamburger" design refers to a distinctive rounded, layered cushion-like seat and backrest profile—typically featuring a wide, cushioned seat pad and a curved backrest with a segmented, soft-look appearance, reminiscent of a hamburger bun. These stools combine playful aesthetics with ergonomic back support, widely used in children's rooms, playrooms, living rooms, and casual seating areas. The core challenges in mold development lie in forming the rounded multi-curved seat and backrest surfaces, structural reinforcement of the backrest-to-seat connection, and surface texture control for the soft cushion-like appearance. Motek addresses these through cavity layout, slider mechanisms, and surface treatment, helping customers achieve stable mass production of hamburger-style backrest stools.

Core Specifications

Product Features

Rounded Multi-Curved Seat and Backrest Forming.

The hamburger stool's defining feature is its rounded, layered profile—a plump seat cushion and a curved backrest that together resemble a hamburger bun. Motek forms these complex curved surfaces through precision cavity machining, with generous draft angles and smooth transitions to ensure clean demolding without surface tearing. The layered appearance is achieved through molded step features or texture bands that create visual separation between the "bun" top, "filling" middle, and "base" bottom.

Backrest-to-Seat Connection Reinforcement.

The backrest-to-seat junction is the critical structural node, bearing the load transferred from backrest pressure during use. Motek reinforces this connection through optimized wall thickness and internal rib layout, ensuring the backrest does not crack or detach under repeated use. Slider or lifter mechanisms form undercut features cleanly.

Soft Cushion-Like Surface Texture.

The hamburger design relies on a soft, cushion-like appearance. Motek applies leather-grain or fine matte texture to seat and backrest surfaces, replicating the look of a cushioned seat without actual padding. Texture depth and pattern are designed to enhance the plush visual effect while maintaining easy-clean properties.

Child-Friendly Safety Design.

Hamburger stools are frequently used in children's rooms and playrooms. Motek forms all edges with generous rounded corners and deburred surfaces to prevent injury. The stool's low profile and wide base provide stability for children climbing on and off.

Balanced Filling of the Curved Body.

The curved seat and backrest create varying wall thickness—thicker at the base and connection areas, thinner at the curved shell surfaces. Motek employs a hot runner system with multi-point gates to ensure balanced melt distribution, preventing short shots in thin curved areas and sink marks in thick transitions.

Stackable and Compact Design.

Hamburger stools are often designed to stack or nest for compact storage. Motek forms stacking features with tight tolerance control, ensuring stools stack securely without wobbling and nest compactly when not in use.
