Frequently Asked Questions (FAQ)
Choosing the right injection molding partner often comes with many questions. At LXG Injection Molding, we want to give you clear, detailed answers so you feel confident every step of the way. Below you’ll find our 15 most frequently asked questions with in-depth responses.
Q1. How quickly can I receive my injection molded parts?
Q2. What industries does LXG Injection Molding serve?
We provide solutions across a wide range of sectors:
- Automotive: dashboards, connectors, bumpers, trim parts.
- Medical Devices: housings, disposables, diagnostic parts, biocompatible components.
- Aerospace: lightweight yet strong housings, brackets, and structural pieces.
- Consumer Products: appliance parts, durable goods, toys, lifestyle products.
- Electronics: casings, connectors, protective housings.
Sustainable Packaging: biodegradable containers and eco-friendly packaging.
Our experience ensures compliance with industry-specific standards (ISO, FDA, UL).
Q3. Do you require a minimum order quantity (MOQ)?
No. Unlike many competitors, we have no minimum order requirement. Whether you need a single prototype, a pilot batch, or millions of units, we adapt to your requirements. Startups, small businesses, and multinational corporations all benefit from our flexible approach.
Q4. Who owns the mold after production?
Mold ownership is flexible. Typically, clients fully own their molds, which remain stored at our facilities for future runs. We also provide shared ownership or project-based licensing when budgets or project scopes require. Every mold is maintained, serviced, and stored under controlled conditions to maximize its lifespan and reliability.
Q5. Can LXG Injection Molding help me reduce production costs?
Yes — cost optimization is part of our DNA. Our engineering team reviews every design with Design for Manufacturability (DFM) principles, suggesting adjustments to:
- Reduce wall thickness where possible.
- Minimize unnecessary undercuts.
- Use family molds to produce related parts together.
Shorten cycle times with hot-runner systems.
Many clients save 10–25% in part cost after applying our recommendations.
Q6. What tolerances can you achieve?
We routinely hold tolerances of ±0.05 mm for most parts. For highly precise applications (medical, aerospace, micro-electronics), we can achieve tighter tolerances validated by:
- CMM (Coordinate Measuring Machine) inspections
- GD&T (Geometric Dimensioning & Tolerancing) checks
Statistical Process Control (SPC)
This ensures every part meets exact specifications, run after run.
Q7. How do you ensure part quality?
Quality is built into every stage of our process. We apply:
- First Article Inspection (FAI) before production approval.
- In-process CMM and GD&T measurements.
- Lot traceability for regulated industries.
- SPC monitoring to detect variations early.
Compliance with ISO 9001, ISO 13485, RoHS, FDA, and UL standards.
The result: consistent, defect-free, high-performance parts.
Q8. What materials can you mold?
We work with over 100 thermoplastics, elastomers, and specialty resins. This includes:
- Commodity plastics: ABS, PP, PE.
- Engineering plastics: Nylon, PC, PBT, PET.
- High-performance polymers: PEEK, PEI, PSU.
- Medical- and FDA-compliant materials.
Sustainable materials: biodegradable resins, recycled plastics.
We also provide advice on resin selection based on performance, cost, and environmental factors.
Q9. Do you offer secondary finishing and assembly?
Yes. Beyond molding, LXG offers:
- Surface finishing: trimming, polishing, painting, pad printing, hot stamping.
- Marking & branding: laser engraving, ultrasonic welding.
- Assembly services: from snap-fit assembly to bonding.
- Clean Room Assembly: Class 8 clean room packaging for medical products.
This saves clients the cost and effort of outsourcing secondary processes.
Q10. How do you protect client intellectual property (IP)?
Q11. Can you manage projects for international clients?
Absolutely. We have delivered over 3,000 molds to 38+ countries. Our global logistics team handles:
- Shipping arrangements with trusted freight partners.
- Export compliance and customs documentation.
Secure packaging to protect molds and parts during transit.
Clients benefit from worldwide reach with localized support.
Q12. What if I already have an existing mold with another supplier?
We specialize in tool transfers. When a client wants to switch suppliers, our team:
- Inspects and refurbishes the mold.
- Adjusts it to meet our production standards.
Runs validation trials before full-scale manufacturing.
This ensures smooth transitions without project delays.
Q13. What is overmolding and insert molding, and do you provide these?
Yes, we offer both advanced processes:
- Overmolding: combines two or more materials in a single part (e.g., soft-touch grips on hard handles).
- Insert molding: integrates components like screws, sensors, or metal reinforcements directly during molding.Both techniques reduce assembly needs, increase strength, and improve functionality.
Q14. What certifications does LXG Injection Molding have?
We comply with multiple international standards, including:
- ISO 9001 for quality managementq
- ISO 13485 for medical device production.
- FDA compliance for medical-grade resins.
UL and RoHS certifications for materials and processes.
This ensures clients receive parts that meet regulatory requirements.
Q15. Why should I choose LXG over other injection molding companies?
Here’s how we stand out:
- No MOQ barrier — we serve startups and global corporations alike.
- Faster lead times — prototypes in days, production in weeks.
- Full-service approach — from DFM to finishing, everything under one roof.
