Engineering Plastic Box

Manufacturer

Full-category case protection solutions · Factory direct · Wholesale / OEM / Global supply

Engineering Plastic Box is an engineered protective case in the protective case family: built by source factory kexinMaterials with IP67 sealing, impact-resistant PP copolymer or rotomolded PE shells and CNC-cut custom foam; wholesale, OEM and export supported.

Key definition

A protective case is a transport and storage enclosure—typically engineered plastic or metal—for equipment, made by injection, rotational or blow molding, with impact resistance, sealing class and custom foam as the core buying criteria.

Standards & Industry Data

Market Size & Growth

The global industrial protective case market was worth about USD 2.05 billion in 2025 and is projected to reach USD 2.88 billion by 2032 (5.0% CAGR). Military & defense is the largest application (~30%), drone-related cases are the fastest-growing niche, North America is the largest region and APAC grows fastest.

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).

IP Ratings (IEC 60529)

In IP67, the “6” means dust-tight (no dust ingress after a 2 kPa vacuum dust test) and the “7” means temporary immersion: the enclosure survives 30 minutes at 1 m depth with its highest point at least 150 mm below the surface, per IEC 60529 Clause 14.2.7.

Typical Applications

  • Equipment and instrument transport
  • Industrial storage and turnover
  • Outdoor and specialty environments
  • Private label and channel distribution

Product Overview

The kexinMaterials Engineering Plastic Box 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 Engineering Plastic Box 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 Engineering Plastic Box 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 Engineering Plastic Box 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

Process is matched to the category — injection for precision sealing, rotomolding for large tough builds, blow molding for lightweight economy — with in-house tooling and batch drop/seal inspection.

Frequently Asked Questions

Which export markets do you serve?

Europe, North America, Southeast Asia, the Middle East, Africa, Russian-speaking regions and South America, with certification and customs documentation support.

Are you a factory or a trading company?

kexinMaterials is a source factory for engineered plastic cases based in Guangdong, China, with injection, rotational and blow molding lines and an in-house tool shop. Factory audits and video tours are welcome.

Can I test samples before ordering?

Yes. Existing-mold products ship as samples for your own drop, immersion and fit testing. For custom projects we can 3D-print a prototype or validate the foam layout in a similar-size shell before committing to tooling, which greatly reduces the cost of getting it wrong.

How much is tooling, and who owns the mold?

Steel injection tooling ranges widely with case size; rotomolding aluminum tooling costs far less. Customary practice is that the customer funds the tool, which is then used exclusively for their orders and not supplied to others. Volume-based tooling rebate arrangements can also be negotiated.

What information do you need for a custom case?

At minimum: the payload's dimensions and weight, the operating environment (immersion, temperature extremes, salt fog), the transport mode (air, sea, road), plus quantity and deadline. For precision foam we also need 3D data or a physical sample to scan.

How can I tell whether a case is genuinely waterproof?

Check three things: a continuous, jointless gasket channel; compression-style latches rather than simple clips; and a pressure equalization valve. Ask for immersion test records, or run a water-fill inversion test yourself — far more reliable than published claims alone.

Key Terms Explained

Injection molding
Molten plastic is injected under high pressure into a steel mold and cooled. It delivers tight tolerances, fine surface finish and fast cycles at low piece cost, but requires higher tooling investment — best for volume production of small and mid-size cases.
Pressure equalization valve
A one-way breather fitted to the case wall that lets air pass slowly while blocking water and dust. It balances internal and external pressure during air freight or altitude change, preventing a vacuum-locked lid or a deformed gasket.
UN packaging certification
United Nations certification for dangerous-goods packaging, requiring drop, stacking, leakproofness and hydraulic tests plus UN marking. A protective case can serve as inner or outer packaging, but the complete system must be certified separately under UN rules.
