Precision Injection Molding Small Parts Manufacturing Services
DongGuan Bohao Industrial Co., Ltd., operating as BOEN Rapid, delivers professional injection molding small parts manufacturing with over 15 years of precision production experience. We provide injection moulding services from prototype tooling to 100-50,000+ production runs, utilising sophisticated moulding technologies and ISO 9001/ISO 13485 certified quality processes. We work with engineering-grade materials such as ABS, PC, PP, PA, POM, TPE and TPU with tolerances up to ± 0.02mm. Our integrated manufacturing platform of mould design, DFM analysis and multi-cavity tooling delivers cost-effective plastic components to medical devices, electronics, automotive and industrial applications.
What Are Injection Molding Small Parts?
Products are precise plastic parts made by injection moulding. In this manufacturing process, thermoplastic granules are melted and injected under controlled pressure into precision moulds.
It results in identical parts with high reproducibility. Small parts normally are from tiny parts weighing less than 1 gram, up to medium sized parts weighing up to 200 grams.
Typical applications include electronic enclosures, medical device parts, consumer product components, and industrial connectors. These components need to be made with dimensional accuracy, surface finish quality and production consistency.
Our Injection Molding Capabilities
BOEN Rapid provides comprehensive injection moulding solutions according to your project requirements. We support fast prototype tooling and high-volume production moulds.
Before going into production, our engineering team will review your design for manufacturability. This first assessment shows potential problems with draft angles, wall thickness and parting lines.
We produce the products by employing moulding equipment from 50 to 500 tonnes with state of art. Multi-cavity moulds minimise your unit costs, and keep quality consistent from one production run to the next.

Key Advantages of Our Service
High Production Repeatability: Once your mold is validated, every part matches the original specifications. This consistency is critical for assemblies requiring precise fit and function.
Cost-Effective Production: Unit costs decrease significantly with volume. Multi-cavity molds further reduce manufacturing expenses by producing multiple parts per cycle.
Complex Geometry Capability: Injection molding creates intricate features including threads, undercuts, thin walls, and detailed surface textures that other processes cannot achieve economically.
Professional Mold Design Support: Our experienced mold designers optimize your tooling for manufacturability, durability, and cycle time efficiency. This expertise prevents costly redesigns and production delays.
Material Flexibility: Choose from engineering-grade thermoplastics with specific properties. Whether you need chemical resistance, heat tolerance, or biocompatibility, we'll recommend the right material.
Industries We Serve
Medical device manufacturers rely on our injection molding services for injection molding small parts components requiring biocompatible materials and strict quality documentation. Each shipment is accompanied by certificates of material and inspection reports.
Our quick tooling services provide electronics companies with a means to evaluate housing designs prior to high volume production. Faster iteration cycles lower your time to market.
Automotive suppliers appreciate our ability to produce tough parts with tight tolerances. Our quality systems assure consistent performance batch after batch.
Industrial equipment manufacturers like our engineering support for complicated assemblies. We can incorporate inserts, overmolding, and secondary procedures into your production flow.
Our Manufacturing Process
Design evaluation is where your project starts. Upload your CAD files and get your first feedback within 24 hours. Our engineers examine part geometry, material selection and manufacturing requirements.
Next is the mould design and manufacture. We develop complete mould layouts with gates, runners, cooling lines and ejection systems. Prototype moulds are typically completed in 2-3 weeks.
Mould performance is validated by production testing. We take first samples, measure important dimensions, and check surface finish quality. You articles OK before they go into full production.
Strict quality rules apply to manufacturing runs. Operators monitor cycle times, temperatures and pressures during manufacturing. Statistical process management helps keep things consistent.
Final inspection involves dimensional inspection, visual inspection, and functional testing as required. Parts ship with the quality documentation you require.
FAQ
Q: What quantities are suitable for injection molding?
A: Injection molding becomes cost-effective starting around 100–500 units depending on part complexity. The initial mold investment distributes across your production volume. Larger quantities dramatically reduce per-unit costs. For very small quantities under 50 units, consider alternative processes like CNC machining or 3D printing first.
Q: How long does injection mold production take?
A: Prototype aluminum molds typically require 2–3 weeks from design approval. Production-grade steel molds need 4–6 weeks depending on complexity. Simple straight-pull molds complete faster than designs requiring slides, lifters, or hydraulic actions. Part production cycles range from 20–120 seconds once molding begins.
Q: Can you make small precision plastic parts?
A: Yes, we regularly manufacture miniature components with features as small as 0.5mm and tolerances to ±0.02mm. Our precision molding machines and quality inspection equipment handle intricate geometries. Medical device components, electronic connectors, and micro-mechanical parts are common applications we support successfully.
Q: What file formats do you accept for quotes?
A: We accept STEP, IGES, STL, and native CAD formats including SolidWorks, CATIA, and Pro/E files. 2D drawings in PDF or DWG format help clarify critical dimensions and specifications. Providing complete documentation accelerates quote turnaround and ensures accurate pricing.
