What Is a Custom ABS Plastic Shell Cover?
A custom ABS plastic shell cover is an injection-molded enclosure manufactured according to customer drawings or 3D files. It protects internal components while providing structural strength, impact resistance, and an attractive surface finish. These parts are widely used in furniture, consumer electronics, medical devices, industrial equipment, and home appliances.

Design Guidelines for ABS Plastic Housing
Following these guidelines reduces tooling cost, cycle time, and defect rates. Our DFM team reviews every submission against these parameters.
| Parameter | Recommended Value | Why It Matters |
|---|---|---|
| Wall Thickness | 2–3 mm (uniform) | Prevents sink marks and uneven cooling shrinkage |
| Draft Angle | 1° minimum (textured: 2°–3°) | Enables clean ejection without drag marks or part sticking |
| Rib Thickness | 40–60% of wall thickness | Adds stiffness without causing visible sink on opposite face |
| Boss Diameter | 2x screw OD | Ensures sufficient material for self-tapping screw engagement |
| Fillet Radius | 0.5T (T = wall thickness) | Reduces stress concentration and improves mold fill flow |
| Shrinkage Rate | 0.4–0.7% (ABS) | Mold dimensions compensated for predictable final part size |
Common Defects to Avoid
- Sink Mark — rib or boss too thick vs. wall
- Warping — uneven wall thickness or cooling
- Short Shot — insufficient fill pressure or thin section
- Flash — mold parting line gap or excessive injection pressure
Goldcattle DFM Support
- Wall uniformity — we flag thickness variation >30%
- Draft check — we verify all vertical faces have adequate draft
- Rib/boss ratio — we adjust dimensions before mold steel cutting
- Moldflow — fill simulation prevents short shots and weld line issues

Frequently Asked Questions
Common questions from OEM buyers about ABS plastic shell cover manufacturing and injection molding service at Goldcattle.
How much does ABS injection molding cost?
Cost depends on part size, cavity count, material grade, and surface finish. Tooling investment ranges from \$3,000–\$25,000 depending on mold complexity and steel grade. Unit part cost decreases significantly with volume — a 2-cavity mold producing 100K+ parts typically achieves under \$1 per piece for small housings. Request a quotation with your 3D files for an exact price.
What is ABS shrinkage rate?
ABS shrinkage is typically 0.4–0.7%, depending on flow direction, wall thickness, and gate location. Mold dimensions are compensated for this shrinkage during design. Glass-filled ABS grades have lower shrinkage (~0.2–0.4%).
How thick should ABS walls be?
Recommended wall thickness for ABS is 2–3 mm with uniform distribution. Variations greater than 30% between thick and thin sections cause sink marks and uneven cooling. Our DFM team reviews every submission for wall uniformity.
Can ABS parts be painted?
Yes. ABS accepts spray painting well, including solid colors, metallic finishes, matte coatings, and custom Pantone matches. Surface preparation (light sanding or primer) ensures adhesion. We provide in-house painting service.
Can ABS parts be chrome plated?
Yes. ABS is one of the best plastics for electroplating due to its etchability. Chrome, nickel, and copper plating are all available. Plated ABS achieves a premium metallic appearance for automotive trim and decorative furniture accents.
ABS vs PC — which is better for enclosures?
ABS offers better impact resistance and easier molding at lower cost. PC offers higher heat resistance, transparency option, and greater structural strength. For most furniture and consumer enclosures, ABS is the cost-effective choice. For electronics requiring higher operating temperature, PC or PC+ABS blend is recommended.
Can ABS be UV resistant or flame retardant?
UV-stabilized ABS grades are available for outdoor applications (furniture, garden equipment). Flame-retardant ABS (UL94 V-0 rated) is stocked for medical, electronics, and appliance enclosures requiring fire safety compliance.
Can you overmold rubber on ABS?
Yes. Two-shot overmolding with TPU or TPE on ABS provides soft-touch grip zones, seals, and gaskets on enclosure surfaces. This requires a two-color injection machine (250T+). Goldcattle offers overmolding capability.
What tolerance can you achieve on injection molded parts?
Standard tolerance is ±0.02 mm for commercial-grade molded parts. Critical features (snap-fit bosses, alignment pins, LCD window openings) can achieve ±0.01 mm with optimized mold design and post-mold CMM verification.
How long does tooling take?
Standard P20 mold: 15–20 days. Hardened H13/718H mold with inserts: 20–30 days. Stainless S136 for medical/optical: 25–30 days. T0 sample is included. Rush scheduling available for urgent projects.
Can you assemble parts after molding?
Yes. We provide sub-assembly services including ultrasonic welding, screw insertion, snap-fit joining, hot-staking, adhesive bonding, and insert placement (threaded brass inserts). Multi-component enclosures can be assembled and tested before shipment.
Can you sign NDA before receiving my drawings?
Yes. Goldcattle signs NDA agreements before reviewing any customer design files. We respect intellectual property and maintain strict confidentiality. Standard NDA template available, or we can sign your company’s NDA form.
