Product Feature Breakdown

Optics

Protecting optics in Custom Roto Case for Surveying is about controlling deflection and humidity: lens-group alignment is measured in micrometres, and shell deformation under stacking or impact transmits through the liner to the barrel. kexinMaterials uses suspended supports in optics cases so equipment never sits on the shell's load path.

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.

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.

Shell Materials Compared (PP / ABS / PE)

Industry data puts PP (polypropylene) at ~55% of plastic protective-case share — strong chemical resistance, low-temperature toughness and cost efficiency; ABS holds ~30% with harder, glossier surfaces; large thick-wall cases favor rotomolded PE. Plastic/polymer cases together account for 63.7% of the industrial protective case market (2025).

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 · Custom tooling

  • Custom Custom Roto Case for Surveying starts from your device dimensions or 3D data; kexinMaterials designs the shell and CNC-cuts EVA inserts to the device outline — existing mold sizes may avoid tooling fees and shorten lead time.
  • From prototype to mass production, kexinMaterials provides structural review, sample confirmation and small-batch trial runs to meet protection grade, shock isolation and access-efficiency requirements.

Product Overview

The kexinMaterials Custom Roto Case for Surveying is one-piece molded from engineering plastics, balancing impact strength, sealing and long-term durability — available from stock or fully customized. Key specs below.

On process: the Custom Roto Case for Surveying can be injection, rotational or blow molded. Injection gives precise sealing and repeatability; rotomolding yields large seamless shells with thick-wall toughness; blow molding suits light, economical builds. kexinMaterials runs all three lines and matches the process to your protection grade and budget.

For interior protection, the Custom Roto Case for Surveying ships with or accepts CNC-cut EVA/PE foam, routed to your equipment's 3D data so nothing shifts in transit; precision instruments can add ESD-safe or cushioned layered structures.

On quality, the Custom Roto Case for Surveying passes batch drop, stack and immersion checks; key models can be tested to MIL-STD-810H for drop and vibration, with material and third-party test reports supplied for export and industry acceptance.

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.

Rotomolded vs injection molded — how to choose?

By size and duty: over 800 mm per side or rough handling favors rotomolding (seamless, high toughness); tight sealing and finish on smaller cases favors injection. We review your spec free of charge.

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.

Tooling cost and timeline?

Depends on geometry: rotomolding aluminum molds run roughly 1/3–1/2 the cost of injection steel molds. Typical tooling takes 35–45 days including trials and first-article approval.

Will they fade or degrade outdoors?

Rotomolding PE can be compounded with UV stabilizers; standard formulations hold up outdoors for 3–5 years. For high-exposure environments such as coastal or high-altitude sites, a higher UV grade and darker color markedly slow chalking and fading.

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.

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.
EVA foam insert
Ethylene-vinyl acetate closed-cell foam: dense, resilient, CNC-machinable and resistant to permanent compression set. In protective cases it is cut to the equipment profile and is the preferred lining for precision instruments and high-value gear.
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.

Common Misconceptions

Is packing a lens tightly the safest approach?

The opposite is true. Tight packing conducts shell impacts straight into the barrel and blocks moisture from dissipating. Optics should be suspended — a continuous elastic medium with clearance between equipment and shell attenuates shock along the transmission path while allowing airflow and dehumidification.
