Plastic Injection molded parts

Custom injection-molded parts fabrication is Sincere Tech’s speciality. Our engineers create self-lubricating, wear-resistive, and maintenance-free plastic injection moulded parts using high-wear engineering-grade plastic materials. Each material can withstand chemicals, filth, and heat and is tailored to your application.

We offer short-lead plastic mold,  injection-molded plain parts and prototypes in 2-3 weeks. Because we use cutting-edge 3D-printed injection moulds, our injection moulding methods are ideal for small to large prototyping. We can design, create, and market products quickly without sacrificing quality.

• Suitable for big orders: Suitable for over 1000 prototypes. ● Minimal, maintenance-free parts with longer service life: Our components last longer without maintenance.

– Fast turnaround: Up to 70% faster than injection molding. – Wide range of materials: Choose from our many high-performance materials to match your needs.

Overview of Custom Injection Moulding

Custom injection moulding involves pumping high-quality material into a mould die or cavity built for specific needs. This approach lets design producers bulk-produce low-volume products. It’s also called plastic injection moulding because it’s done this way.

Molten polymer is forced into a mould to shape the product. The polymer cools and solidifies to form the mold-released part. The custom injection-molded parts or products manufacturing technique is flexible and can be utilised for medium production for a few hundred to several thousand identical moulded components. The procedure is popular for its cost-effectiveness and enables automotive, aerospace, and electronics companies make prototypes for functional testing and aesthetic improvements. 

Plastic Injection Moulding Materials Custom

Custom injection moulding uses polymers with different melting temperatures and properties that can be tailored to a specific application. These thermoplastics are used to make high-quality injection moulded products. 

ABS  

ABS is a popular thermoplastic with strong impact strength, flexibility, and low density. It cannot withstand chemical, electrical, or UV exposure. ABS’s strength makes it popular in toys, appliances, and car parts.

LDPE and HDPE  

Multipurpose thermoplastics with strong tensile, impact, and moisture resistance. HDPE and LDPE, which is softer, are utilised in consumer and industrial products. The durability and bendability of both materials are valued.

PC, a lightweight, high-gloss matte material, is a robust and clear alternative to glass. Its high resistance, impact, and mechanical strength make it excellent for bulletproof glass.

Nylon polyamide  

Electrical characteristics, mechanical strength, heat, wear, and chemical resistance make nylon a popular thermoplastic. It is utilised for injection moulded mould parts in the medical and automotive industries due of its durability and performance.   

High-impact polystyrene  

HIPS, an inexpensive impact-modified crystalline styrene-rubber copolymer, is used to make disposable cutlery and toys. Non-toxic, food-contact, flexible, and affordable.

Plastic (PP)  

PP has great impact strength, chemical resistance, and stress resistance. Its high melting point makes it perfect for food industry equipment that must be robust and safe.

These materials are selected based on the application to optimise bespoke injection-molded part performance and durability.

Tool Engineering and Design

The mould or die that shapes the material in injection moulding called the tool. A negative cavity recreates the part’s shape with the right proportions to allow injection and cooling of the material. Depending on the necessity, custom moulded plastic parts may require multiple tools. More tools initially increase the cost, but they reduce the cost per piece over time, making mass manufacturing reasonable.

An injection moulding machine’s mould base holds these tools. We fit insert tooling onto polymer moulding mould bases since mould bases are expensive.

Our genuine engineers analyse DFM analysis to material, technique, tool design, and process optimisation while making custom-molded plastic components. They use the correct manifold and runner systems, moulding techniques, and functions without extras, saving you money. The high-tech program universally converts virtual technical 2D or 3D g-code to m-codes for correct tooling in the tool room.

Professional tool manufacturers are available at Sincere Tech for tool building and mould maintenance. Our expert engineers and manufacturers construct accurate tools to meet the standard by selecting the proper steel grade tool for the process. CNC machines, precision optical laser engraving machines, laser and tig welders, EDM, heat treatment, grinding, polishing, and plating allow us to develop and maintain high-performance tools.

Lean Moulding

Our in-house production operation uses high-speed feature machines and presses with quick tooling changeovers for each batch. Standard, efficient machines produce millions of excellent, low-cost moulded plastic parts daily.

Tools Maintenance

Our value-added customer services enable high-quality custom tool manufacture. After each use, our mould changeover department cleans and inspects tools, re-plating or repairing them as needed before storing them for the next production cycle.

Advantages of Custom Injection Modification

Custom injection moulding is versatile and ideal for complex, small parts with stringent standards. It is cost-effective for high-volume manufacture of similar parts. It forms plastic faster and better than machining or additive manufacturing. Its considerable design freedom allows it to form and make pieces of varied shapes, sizes, and colours. Polypropylene, ABS, nylon, and polycarbonate can be used to suit application requirements for rigidity and ductility.

Who to Use? Custom Injection Moulding

Companies who wish to make sophisticated products in large or small quantities should use custom injection moulding. Automotive, electronics, and medical industries need customised components swiftly and correctly.

Custom injection moulding may create sophisticated parts in hours to days, depending on intricacy and size. This helps create a prototype and start mass production quickly. 

If the part design fulfils injection moulding standards, custom injection moulding is cheaper than machining or 3D printing. Better quality and uniform surface finish are also generated by injection moulding than milling.

Customers also benefit from faster lead times and a variety of thermoplastics like ABS, polypropylene, nylon, and PEEK. This adaptability ensures the product meets criteria and performance.

Increased Customer Support

Sincere Tech moulding is ISO 9001:2015 certified, demonstrating our quality control and guarantee.

ISO standards ensure our services have the best business processes and quality management systems to satisfy customers.

Our quality department uses cutting-edge technology, a four-step inspection system, and SPC to ensure manufacturing conformity. Instead of using the naked eye, we use advanced measuring devices to assure uniform proportions regardless of complicated designs to ensure items fit exact dimensions and standards. This method boosts efficiency and allows more frequent and precise inspections.

From mould setup to production runs, our quality assurance is stringent. The first pieces following mould setup are evaluated to verify product quality before manufacturing. Product visual inspection is done by machine operators, while in-process inspectors do visual, dimensional, and functional inspections periodically. Visually checking labels for quality, quantity, and accuracy is the final step before packaging.

SPC collects and analyses statistical data from processes, product measurements, and machines to control quality. This approach improves efficiency, productivity, and reduces off-standard products and scrap, lowering customer costs.

We value product quality at Dong Guan Sincere Tech. Our skilled engineers can assist with PPAP, ISIR, FAIR, IMDS, Reach, RoHS, and other certifications and reports.
