Custom PC/ABS Injection Molding Solutions
PC/ABS combines the structural integrity of polycarbonate with the processing ease of ABS, producing parts that are impact-resistant, dimensionally stable, and visually consistent. PPMolding handles the moisture control, shrinkage management, and gate placement required to keep your parts within both aesthetic and functional specifications.

PC/ABS Material Characteristics
PC/ABS delivers a balanced performance profile: it is less brittle than pure PC and offers better heat resistance than pure ABS. The table below maps each property to the design decisions it enables on your part.
PC content is typically formulated between 50% and 80% of the blend, tuned to balance impact strength, heat resistance, and flow for the target wall thickness and geometry.
Pure PC is tough but hard to process. Pure ABS flows easily but softens under heat. The alloy bridges that gap, widening the design envelope without driving tooling complexity.
| Property | Typical Value / Characteristic | Impact on Your Part |
|---|---|---|
| Heat Resistance | 100°C – 120°C range | Prevents warping in electronics housings |
| Impact Strength | High | Durable enough for drop-sensitive devices |
| Processing Temp | 230°C – 270°C | Requires precise thermal control |
| Shrinkage Rate | 0.5% – 0.7% | Predictable for tight-tolerance parts |
| Surface Finish | Smooth / High Gloss | Excellent for cosmetic consumer products |
| Typical Applications | Automotive trim, laptop housings, power tool casings | Reliability in demanding environments |
Engineered for PC/ABS, from Tooling to Finishing
PPMolding manages the full production cycle on injection molding machines from 50 to 1,000 tons, supporting prototype runs and bridge tooling through full-scale mass production.
Molds Designed Around PC/ABS Flow
PC/ABS is thermally and shear sensitive. Our tooling is engineered around its flow behavior to keep cosmetic surfaces clean and structural sections consistent.
- Gate Placement: Strategic gating to minimize weld lines in visible areas.
- Venting: Optimized air evacuation to prevent burn marks, a common risk with high-heat engineering plastics.
- Cooling Channels: Conformal cooling to ensure uniform shrinkage and prevent warping.
Prototype Runs
Aluminum or soft-steel tooling for fast iteration on geometry, fit, and surface review.
Bridge Tooling
Limited production runs for market testing, validation, and pre-launch inventory.
Mass Production
Hardened production tooling run on 50–1,000 ton presses with controlled cycle times.
Pad Printing
Marks, logos, and ratings applied to curved and textured PC/ABS surfaces.
Laser Marking
Permanent, high-contrast identification without compromising surface finish.
Painting
Custom color matching and texture finishes for cosmetic consumer products.
Ultrasonic Welding
Clean, repeatable joins for multi-part assemblies without fasteners or adhesives.
Design for Manufacturing Review
Successful injection molding starts before the mold is cut. Our engineers review your 3D models and 2D drawings to optimize them for PC/ABS production. Addressing these factors early reduces the likelihood of mold modifications and keeps your production schedule on track.
Every DFM review is conducted by molding engineers, not sales staff, so the recommendations you receive are grounded in tool-room reality.
Wall Thickness
Maintaining uniform thickness to prevent sink marks and internal stress concentrations.
Draft Angles
Ensuring easy ejection to protect the high-gloss surface finish that PC/ABS is selected for.
Ribs and Bosses
Designing structural supports that do not cause cosmetic defects on the opposite side of the part.
Tolerances
Evaluating the shrink rate of your specific PC/ABS grade to confirm final parts meet dimensional requirements.
PC/ABS Built for Demanding Environments
Our PC/ABS manufacturing services support a broad range of sectors that require high-quality plastic components under thermal, mechanical, and cosmetic stress.
Devices & Enclosures
Laptop housings, router enclosures, and handheld device cases.
Interior & Trim
Dashboards, interior trim, and structural brackets.
Consumer Hardware
Vacuum components, blender housings, and control panels.
Equipment & Boxes
Protective covers, machine housings, and electrical boxes.
