CUSTOM MOLDING
Your cap idea,
built in 15 days.
Most suppliers send your mold drawings to a third-party toolmaker. We don’t. Our engineering team designs, machines, and tests every cavity in-house, so you get faster samples, tighter tolerances, and zero surprises.
From your sketch to mass production
Every custom mold project follows the same transparent 4-step process. You'll see exactly where your project stands at each stage, with real samples in your hands before a single production unit ships.
01
Day 1–2 · Brief
Tell us what you need,
and we'll handle the rest
No technical drawings required. Share a reference product, a rough sketch, or just a description. Our engineers translate your brief into a detailed 3D specification.
- Neck finish & thread standard (e.g. PCO-1810, 28mm)
- Industry application & performance requirements
- Material preference: PP, PE, PCR, bi-color, TPE
- Annual volume estimate for cavity count planning
02
Day 3–5 · Engineering
CAE simulation before we touch any steel
Before CNC machining begins, we run a full mold-flow simulation. This catches weld lines, air traps, and sink marks on screen — not on your sample. It’s why our T1 approval rate is above 90%.
- Mold-flow analysis: filling, packing, warpage
- Gate location & cooling channel optimization
- Wall thickness & parting line review
03
Day 6–12 · Tooling
Steel machined in our own workshop
Our tooling floor runs high-speed CNC centers and EDM finishing machines. We use P20 or H13 tool steel depending on volume requirements — and every cavity is polished to the specified surface finish before trial.
- P20 steel: standard volumes up to 500K cycles
- H13 steel: high-volume runs 1M+ cycles
- EDM for fine details — logo embossing, textures
- 3-coordinate CMM verification before trial shot
04
Day 13–15 · Sample & Approval
Physical sample in your hands before production
T1 samples are shot on our production injection machines — not prototype equipment. What you approve is exactly what will run in production. Samples ship with a full dimensional report and material certification.
- Dimensional inspection report (every key dimension)
- Torque test, drop test, seal test performed
- Color-matched samples if Pantone reference provided
- Modifications turned around in 3–5 days if needed
Innovations protected by
8 national patents
Our R&D team holds both invention and utility patents covering closure structures, pump mechanisms, and proprietary polypropylene materials — the foundation of everything we make.
Before you start
Who owns the mold after the project?
You do. Once the mold cost is settled, ownership transfers to you. We store it in our tool room at no charge and maintain it between production runs.
What's the minimum order for a custom mold project?
Mold investment starts from approx. $2,000–$6,000 USD depending on complexity. Production MOQ is 50,000 pcs. We’re flexible on first orders for established brands.
Do I need to provide technical drawings?
No. A reference sample, a sketch, or even a clear photo is enough to start. Our engineers produce the 3D model and DFM report — we’ll share it for your review before cutting any steel.
Can I request changes after seeing the T1 sample?
Yes. Minor adjustments (wall thickness, texture, logo depth) are typically turned around in 3–5 days. We include one round of T2 modifications in the mold price.
