A Real Factory Behind Every Case
Dongguan Hongchenda Packaging Products Co., Ltd. — Humen Town, Dongguan, Guangdong, China. We mold, cut, sew and pack under one roof, so your custom EVA case never depends on a subcontractor's schedule.
Molding to Packing, In-House
Vertical integration is why we hit 15–25-day lead times on custom tooling. Every critical step happens in our own workshop:
- EVA molding — 8 molding presses form high-density shells to your exact cavity design.
- Precision cutting — laminating, cutting and die-cutting for shells, foam inserts and fabrics.
- Sewing — flat-bed and high-speed machines for zippers, linings, straps and binding.
- Custom branding — embossing, debossing, woven labels, screen print, heat transfer, custom zipper pulls.
- Private-label packing — retail-ready polybag, gift box or PDQ to your spec.

From EVA Sheet to Finished Case
Every custom case passes through the same six-stage process in our own workshop — no subcontracting, no handoffs, no surprises.
Mold Design & CNC Mold Making
Your product's 3D cavity design is translated into a precision aluminum mold, machined on CNC centers. Mold accuracy is what decides how precisely the finished case hugs your product.
Material Cutting
EVA sheets, foam and outer fabrics are precision-cut to pattern. Clean edges at this stage mean clean seams on the finished case.
Hot-Press MoldingCore step
The heart of the process: EVA blanks are formed under 150–200°C controlled heat and pressure, taking the mold's exact shape with consistent density and rebound.
Trimming & Finishing
Flash and excess material are trimmed away; edges are finished smooth for a clean, retail-ready profile.
Lamination & Sewing
Linings are laminated to the shell, then zippers, piping, straps and binding are stitched in on flat-bed and high-speed machines.
Assembly & QC
Hardware is fitted and every case is inspected against the approved sample — dimensions, stitching, branding — then packed to your specification.
Three Roles Decide the Quality of Every Case
The mold maker. A mold accurate to a tenth of a millimeter is the difference between a case that fits like a glove and one that rattles. Our mold makers obsess over cavity geometry, draft angles and parting lines before a single sheet is pressed.
The molding technician. Hot-press molding is a craft of timing — temperature, pressure and dwell time tuned to each EVA formulation and shell thickness. Get it wrong and the shell warps or loses rebound; get it right and it holds its shape for years.
The QC engineer. The last pair of eyes compares every production batch against your approved sample: dimensions with calipers, zipper function, stitch density, logo placement. Nothing ships until it matches.
Checked Three Times Before It Ships
A dedicated 5–10 person QC team owns quality end to end — no batch leaves until it matches your approved sample.
1 · Incoming Inspection
EVA sheets, fabrics, zippers and hardware are checked against spec on arrival. Off-spec material never enters production.
2 · In-Process Control
Molding temperature, cut dimensions, stitch density and zipper function are verified at each station, every shift.
3 · Pre-Shipment Audit
Finished goods are AQL-inspected against the approved sample — dimensions, branding placement, packaging — before dispatch.
Design Support, Not Just Production
Our 5–10 person R&D team turns your idea into a manufacturable product: 3D cavity design, material selection, branding mockups and physical samples in about 7 days.
