Which deodorant stick parts need injection molds?
Common molded parts include the base, cap, screw, elevator platform, inner support, and related rotary mechanism parts. Songrock confirms the mold split after reviewing the full package structure.

Custom Deodorant Stick Injection Mold for Smooth Rotary Packaging
Songrock develops deodorant stick injection molds for bases, caps, elevator platforms, screws, support parts, and rotary advancement systems. These packages require precise concentricity and smooth movement, so our tooling work focuses on fit between the screw, base, and platform, controlled shrinkage, clean release, reliable assembly behavior, and smooth filling-line operation.

Injection mold advantages
Deodorant stick molds built for rotary fit, concentricity, and smooth product lift
Deodorant stick packaging depends on the interaction between the screw, base, elevator platform, cap, and support structure. If shrinkage, roundness, thread form, or fit is inconsistent, the rotary mechanism can feel tight, slip, or jam during filling and consumer use.
Songrock studies the complete movement system before mold production. We control critical dimensions, thread geometry, cavity accuracy, steel strength, and release behavior so molded parts can assemble smoothly and keep stable advancement through the product life cycle.
Product FAQ
Questions before starting this category project
How do you prevent tight or stuck deodorant stick rotation?
We review thread geometry, concentricity, shrinkage, platform fit, resin behavior, and assembly clearance. Trial parts are checked for smooth rotary advancement and repeatable movement.
Can one mold design support different deodorant stick capacities?
Related capacities may share design principles, but mold sharing depends on diameter, height, screw pitch, cap fit, and platform structure. Songrock evaluates the range before recommending inserts or separate molds.
What defects are common in deodorant stick molded parts?
Common issues include ovality, thread deformation, sink marks, loose caps, tight screws, poor platform fit, and release marks. Mold design and trial tuning focus on these functional risks.
What should be supplied for a deodorant stick mold project?
Please provide assembled samples, part drawings, resin, filling process requirements, movement expectations, annual volume, target cavity count, and any current problems with rotation, cap fit, or assembly.
