China Abs Plastic Injection Molding

Our ABS Molding Process — Step by Step

Here’s a transparent look at how LXG Mold Tooling handles your ABS plastic injection molding project — from your initial concept to your delivered parts.

4.1 Initial Consultation & Quotation

You reach out with your CAD files, drawings, or even a rough concept. We evaluate:

• Part geometry and complexity

• Functional requirements (strength, heat resistance, surface finish)

• Expected volumes

• Material grade (standard ABS, flame-retardant ABS, ABS-PC blends, etc.)

Then we prepare a quote that includes mold design, mold cost, molding cost (per piece), and lead times. We strive to be transparent — no hidden fees.

4.2 Design for Manufacturability (DFM) Review

Before building anything, our engineers perform a DFM review. We check:

• Wall thickness uniformity

• Gate location and runner design

• Draft angles

• Potential sink marks, warpage, weld lines

• Focus on strategies to reduce cycle time and reject rates

We’ll send you feedback and suggestions to improve your design for ABS molding.

4.3 Mold Tooling & Fabrication

Once design is approved, we manufacture the mold (often made of P20, 718, or specialized tool steels). We perform:

• Precision machining (CNC, EDM, wire cut)

• Polishing, mold surface treatment

• Testing of mold fitting, alignment, venting

• Temperature control systems embedded

Because we are a vertically integrated ABS molding supplier, we handle both the mold and molding in-house — reducing communication overhead and risk.

4.4 Mold Trial / Sample Runs

We perform trial runs to refine process parameters. This includes:

• Injecting trial parts

• Measuring with CMM and other metrology tools

• Adjusting injection speed, pressure, temperature

• Checking cosmetic quality, dimensional accuracy

We share these samples with you. Based on your feedback, we make tweaks until parts are fully approved.

4.5 Mass Production / Full-Scale Injection Molding

With a validated mold and process, we move into full production. Our ABS molding machines run continuously under SPC (Statistical Process Control), ensuring each part meets spec.

We maintain consistent material drying, throughput, cooling control, and reject monitoring to maintain high yield.

4.6 Secondary Operations & Finishing

If your parts require:

• Overmolding

• Insert / in-mold assembly

• Texturing, painting, pad printing

• Ultrasonic welding, surface treatment

We handle these downstream steps, consolidating your supply chain.

4.7 Quality Control & Inspection

Every batch is subject to:

• First Article Inspection (FAI)

• Coordinate Measuring Machine (CMM) tolerances

• Visual checks for defects (sink, warp, flashes)

• Statistical sampling for long runs

Only parts that pass all checks leave our factory.

4.8 Packaging & Global Shipping

We pack parts safely (anti-static, inner boxes, pallets) and coordinate logistics. We’ve shipped ABS molds and parts to 38+ countries, so we know how to make sure your order arrives intact.

5. What Makes a Great China ABS Molding Supplier (and Why LXG Mold Tooling Excels)

Many suppliers promise “cheap molding in China,” but few deliver consistency, transparency, and reliability. Here’s what distinguishes a great China ABS molding supplier, and where LXG stands out:

Because LXG is built for long-term partnerships, we invest in these areas so you don’t worry.

6. Tips for Ordering ABS Parts from China

If you are a buyer considering working with a China ABS plastic injection molding supplier, here are practical things to look out for — to avoid pitfalls:

1. Request mold flow analysis or simulation results — see how filling, cooling, and warpage are predicted.

2. Ask for prior sample photos + supplier references — validate their track record.

3. Insist on material traceability — ABS grades do vary.

4. Agree on tolerances clearly — ABS can shrink, so dimension control must be defined.

5. Plan for moisture control — ABS must be dried to <0.05% moisture or defects occur.

6. Check gate and runner design — excessive runner waste or poor gating kills yields.

7. Ask about mold warranty and maintenance schedules — molds age over time.

8. Split mold cost and per-part cost — it helps when scaling or replacing molds.

9. Set up inspection protocols — get First Article samples, use CMM, establish acceptance criteria.

10. Arrange logistics & packaging carefully — ABS parts are sensitive to scratches and deformation.

If your supplier can explain these areas intelligently and has systems to manage them, that’s a very good sign.

7. Common ABS Injection Molding Challenges & How We Handle Them

Even though ABS is a well-known plastic, molding it well is not trivial. Here are typical challenges and how LXG tackles them:

• Warping / Shrinkage — We use uniform wall thickness, balanced cooling, and proper annealing.

• Sink marks / internal voids — Optimized gate placement, holding pressure time, and melt temperature control.

• Flow lines, weld lines, gloss differences — Fine-tuned injection speed & mold surface finish.

• Thermal degradation — Use correct temperature windows, minimize residence time.

• Moisture-induced defects — Strict material drying and vacuum hoppers.

• Mold wear / maintenance — Use durable tool steel, schedule preventive maintenance, monitor wear.

• Surface finish issues — Polishing, texturing, coatings to meet aesthetic specs.

Because we design and run molds ourselves, we can adapt and correct problems quickly — rather than passing issues back and forth with a 3rd-party mold house.

8. Use Cases & Applications — ABS Parts We Manufacture

When you work with a China ABS molding supplier like LXG, here are application domains where we deliver value:

• Consumer Electronics — Housings, bezels, faceplates (ABS provides good finish and impact resistance)

• Automotive Interior & Trim — Dashboard parts, air vent bezels, plastic trims

• Medical Devices / Enclosures — Especially where mechanical safety and cleanability matter

• Home Appliances — Control panels, covers, aesthetic shells

• Toys & Consumer Goods — ABS is ideal for toys due to strength and moldability

• Industrial / Tools — Lightweight cases, protective shells, components

Because ABS supports coloring, plating, painting, and overmolding, we can deliver parts that are both functional and attractive.

9. Why Partner with LXG Mold Tooling for China ABS Molding

Let me make a direct case for choosing LXG Mold Tooling:

• You’ll work with a China ABS plastic injection molding company that treats mold-making and molding as one integrated service.

• We offer transparent quoting, separating mold cost and part cost, with no hidden markups.

• Our technical team offers design feedback to reduce risks early.

• We have rigorous quality systems (CMM, SPC, FAI) so you get consistent parts.

• We support scalable production — you can start with small runs and grow.

• We protect your IP via NDAs, secured data, and controlled access.
