Product Feature Breakdown

Outdoor / field

Field temperature swings create pressure differentials in sealed cases: OEM Roto Case for Field Ops heats up in daytime sun and cools sharply at night, drawing moist air inward over repeated cycles. An automatic purge valve is mandatory rather than optional on outdoor sealed cases; kexinMaterials fits one across the sealed range.

Standards & Industry Data

Extreme Temperature Performance

Engineering-grade cases typically operate from -30°C to +80°C (military testing follows MIL-STD-810H Methods 501.7/502.7 for temperature and 503.7 for thermal shock, cycling as wide as -40°C↔+71°C). For cold climates choose PP copolymer or PE shells — standard ABS embrittles at low temperatures.

Military Drop Test (MIL-STD-810H, Method 516.8 Proc. IV)

MIL-STD-810H (8th revision, 2019; 29 test methods) requires transit-drop samples to survive 26 drops from up to 5 ft (1.5 m) onto steel-backed concrete in varied orientations. Versus 810G, the H revision raised drop height from 4 ft to 5 ft and switched to a harder steel-backed surface.

Rotomolding Parameters (LLDPE)

Rotomolded cases use LLDPE powder with typical wall thickness of 5–10 mm (process range 1–16 mm), naturally thicker corners, and no weld seams or trim waste. Tooling costs roughly 1/5–1/10 of injection molds with ~±5% dimensional tolerance — ideal for large, thick-wall cases in small-to-mid batches.

Typical Applications

  • Custom rotomolded transit cases for heavy equipment
  • High-seal injection molded instrument cases
  • Blow-molded tool box contract manufacturing
  • Specialty compound case development
  • Full ODM outsourcing for case brands
  • Export-spec case re-engineering

Sourcing & Selection Tips · OEM / private label

  • OEM Roto Case for Field Ops is available for OEM/private-label: kexinMaterials customizes shell, insert and packaging so finished-goods brands turn protective packaging into part of the product experience.
  • OEM programs can reuse kexinMaterials's existing molds to avoid tooling fees, with branded silk-screen, CNC-cut inserts and manuals to shorten time-to-market.

OEM / ODM Custom Manufacturing

kexinMaterials runs full OEM/ODM programs on the OEM Roto Case for Field Ops: drawing/sample quotation, 3D structural design, in-house tooling (35–45 days), pilot runs and mass production — under NDA throughout.

The standard private-label flow for the OEM Roto Case for Field Ops: requirement review → proposal & quote (1–3 days) → sample approval (7–15 days) → production (15–30 days) → QC & shipment. Logos via silk print, laser engraving, hot stamping or in-mold labeling.

Need speed instead of tooling? Choose tooling-free private label: adopt an existing kexinMaterials mold, switch colors and branding, and launch from just 100 pcs — the fastest route for new case brands.

Manufacturing Process

The injection line owns precision and sealing, the rotomolding line owns size and toughness, and the blow molding line owns weight and cost — all sharing one tool shop and QC system, so one supplier covers a multi-process purchasing mix.

Frequently Asked Questions

What is the MOQ?

50 pcs on existing molds. Tooled projects are typically planned on annual volume with first orders from around 500 pcs, negotiable by model.

Can rotomolded cases be forklifted and stacked?

Yes. We offer bases with forklift channels and stacking lugs. Empty cases stack four to six high; loaded stacking height is calculated from per-case load and warehouse clearance. Tell us your racking dimensions and load ratings if the cases will live in a pallet rack.

How thick can rotomolded walls be?

Typical walls are 3–6 mm, rising to 8 mm or locally thicker for heavy-duty and machinery cases. Thicker is not automatically better: wall thickness must be designed together with ribbing and span, or you simply add weight and cost with little impact benefit.

Can rotomolded cases be insulated or double-walled?

Yes. Rotational molding naturally forms a double wall in one shot; filling the cavity with PU foam produces an insulated case for cold chain, vaccine and low-temperature sample transport. Lightweight fills can instead provide buoyancy or weight savings.

How do ODM projects work?

You bring requirements and positioning; we handle industrial design, structure, prototyping, tooling and production. IP ownership is contracted, with NDA throughout.

Rotomolded or injection molded — how do I choose?

It comes down to size and load. Injection molding suits small and mid-size cases with tight tolerances, fine surfaces and low piece cost but expensive tooling. Rotational molding suits large and oversize cases, delivers 4–8 mm seamless walls with superior toughness, and needs cheap tooling but slower cycles. Above roughly 800 mm internal length, or for heavy stacking loads, rotomolding wins.

Key Terms Explained

Rotational molding
A process in which polyethylene powder is heated inside a biaxially rotating mold so the melt coats the cavity evenly. It yields seamless, tough walls, supports double-wall sandwich construction and uses low-cost tooling — ideal for large and oversize cases.
OEM / ODM
OEM means manufacturing to the customer's design under the customer's brand; ODM means the factory designs the product and the customer rebrands it. In case sourcing, private-labeling an existing shell is OEM, while commissioning a new shell and interior design is closer to ODM.
ESD / antistatic
Conductive masterbatch or antistatic lining brings surface resistance into the 10^6–10^9 Ω range so static cannot build up and damage electronics. It is a routine requirement in electronics manufacturing, semiconductor and precision instrument handling.

Common Misconceptions

Is waterproofing enough for an outdoor case?

Waterproofing only addresses liquid water. The three real outdoor damage mechanisms are UV ageing, the breathing effect from temperature swings (drawing in moisture that condenses inside), and sand abrasion of moving parts. Confirm the UV rating, the presence of a purge valve, and dust-shielded latch and hinge design.
