SERVICES
ABS Injection Molding
We mold ABS (and compatible grades) for functional, structural and aesthetic parts — from low-volume bridge production to high-volume runs.

HOW IT WORKS
From Inquiry to Delivery
CHALLENGES
Challenges This Service Solves
Flash (burrs)
Overpacking at the parting line from excessive injection pressure or worn mold steel.
Sink marks
Thick sections shrink more than thin walls, leaving visible depressions on the surface.
Silver streaks & bubbles
Moisture in undried ABS flashes to steam during injection, leaving silvery trails.
Weld lines
Meeting melt fronts fuse weakly at gates and around core obstructions.
Warpage
Non-uniform cooling and wall imbalance distort the part after ejection.
Flow marks
Surface waves from hesitation or variable melt temperature.
FAQ
ABS Injection Molding — FAQ
Can you help with product development?
Yes. From design review and material selection to prototyping, tooling and mass production — our engineers support you through the entire product lifecycle.
Do you ship internationally?
Yes. We ship worldwide via air and sea freight, with export packing, documentation and delivery tracking handled by our team.
What quality inspections do you perform?
First article inspection, dimensional measurement, material verification and surface checks — with inspection reports provided per batch. Full details are agreed before production.
What is the difference between rapid and production tooling?
Rapid tooling uses softer materials and simplified construction for fast, low-cost validation runs (hundreds to low thousands of parts). Production tooling uses hardened steel for high-volume, long-life programs.
How long does injection mold making take?
Rapid tooling prototypes can be ready in days; production tooling typically takes several weeks depending on complexity, cavity count and steel grade. We confirm a detailed schedule with your quotation.
Do you provide DFM feedback?
Yes. Every quotation includes a design-for-manufacturing review: draft angles, wall thickness, gate and weld-line locations, tolerance recommendations and cost-saving suggestions — before any tooling is cut.
What file formats do you accept?
We accept STEP, IGES, STL, X_T and 2D drawings (PDF or DWG). A 3D model lets us quote most accurately; 2D drawings are used to confirm critical tolerances and specifications.
How do I get a quote?
Upload your 3D file (STEP, IGES, STL or X_T) through the quote page, or email it directly. Our engineers review the design, run a DFM check and send you a detailed quotation — usually within one business day.

What Makes ABS One of the Most-Molded Thermoplastics?
ABS combines rigidity, impact toughness and a finishing-friendly surface — it is the most-used resin in FirstMold's injection molding projects (https://firstmold.com/abs-injection-molding/). MOLDITQUICK (Dongguan Guohong Precision, 10000 m², 280 staff) molds the same grades for automotive, electronics and medical programs.
High dimensional stability — molded ABS holds its designed size well, which matters for parts like engine-compartment brackets that must mate with other components.
High replication precision — complex shapes, fine textures and tiny buttons come out consistent shot after shot across automated Sodick injection cells.
Good impact strength and rigidity — tough enough for structural housings and enclosures that get handled daily.
Design freedom — complex shapes and multi-function parts can be integrated into a single molding, cutting part count and assembly steps.
Finishing-friendly — ABS takes painting, chrome plating, EMI shielding, pad printing and laser etching well, widening the cosmetic options.
Strong weld-line and gate experience — automotive and electronics parts are proven out in DFM before steel is cut, keeping first-shot risk low.
ABS Processing Parameters We Control
Barrel, mold and shrinkage windows per published ABS molding data (https://firstmold.com/abs-injection-molding/); every window is verified in-house on our Sodick presses under IATF16949 / ISO13485 / ISO9001 control.
| Parameter | Recommended Range | Why It Matters |
|---|---|---|
| Barrel temperature | 210–250 °C | Melt must be fully plasticized without degrading; keep the window tight for consistent viscosity. |
| Mold temperature | 40–80 °C | Hotter molds improve gloss and flow; colder molds shorten cycle time. |
| Mold shrinkage | 0.4–0.7 % | Lower than PP or POM — cavity sizing compensates; critical for mating parts and snap fits. |
| Drying | 80 °C, 2–4 h before molding | ABS is hygroscopic — moisture causes silver streaks (splay) and weak weld lines. |
| Typical wall thickness | 1.0–3.5 mm | Uniform walls reduce sink marks and warpage; ribs should run about half the wall thickness. |
