The plastic injection molded cases of the projector need to account for functional, durability and appearance functions as much as design, material and process are involved.

ZIBO HUIWENcan personalize plastic shell production according to customers' requirements.

Plastic cases made by ZIBO HUIWEN are Feature  by:

1. Material Characteristics

- High Temperature Resistance: The projectors give off heat while working, and thus the enclosures should be made of high-temperature-resistant plastics (such as ABS, PC/ABS alloy, flame retardant PP), to avoid deformation or discharge of toxic materials.

- Lightweight: Common engineering plastics (such as ABS, PC) are used for providing strength without increasing the weight of the machine too much, so that it can be easily carried or mounted.

- Fire Retardation: They gain UL94 V-0/V-1 fire retardant testing certifications to block fire risks.

- Eco-friendliness: Some enclosures are constructed of recyclable plastic (e.g., recycled ABS) or achieve RoHS standards.

2. Structural Design Functions

- Maximizing Heat Dispersion: Adopt heat dispersion holes, duct components, or fuse with metal parts to enhance thermal conduction (e.g., metal-bracketed designs).

- Modular Assembly: Employ split design (e.g., front cover, back cover, lens frame) for ease of injection molding production and then maintenance.

- Thin-walled Design: Add ribs, snap-fit designs, etc., to the structure to reduce material usage while maintaining strength.

- Dust and Drop Resistance: Some models employ sealing ring designs or rubber edge treatments to provide higher levels of protection (e.g., IP5X).

3. Surface Treatment Processes

- Texture Processing: Sunning and embossing process enhance the surface friction (anti-slip) or hide the injection molding imperfections.

- Gloss/Matte Finish: Achieve mirror or matte finishes with spraying, UV coating, or IMD (In-Mold Decoration).

- Anti-fingerprint Coating: Prevent the oil stains due to users' touches, which make the product more attractive.

4. Function Integration

- Interface Reservation: Precise hole drilling to accommodate HDMI, USB and other interfaces. Detachable dust-proof covers are implemented in some designs.

- Acoustic Optimization: Inner structure design can reduce the resonance of fan sound (e.g., adding slots for sound-absorbing cotton).

- Aesthetic Design: Streamlined look, hidden buttons or RGB light strip slots, which enhance the technological beauty of the product.

5. Production and Cost Considerations

- Mold Precision: High-precision molds ensure the joint gaps are small (e.g., ≤ 0.5mm), enhancing the texture as a whole.

- Batch Efficiency: Injection molding is cost-effective for bulk production, reducing the unit cost.

- Post-processing Minimization: By using two-color injection molding or insert injection molding, secondary processing stages can be minimized.

The projector casing design must balance between heat dissipation, weight, cost and end-user experience. Various positioning products (e.g., home portable type vs engineering projectors) will have tremendous variations in structure and material choice.
