In an era where the manufacturing industry is transitioning toward "high precision, customization, and rapid responsiveness," machined parts,
injection molding process, and custom plastic injection molding have become the three core pillars supporting the upgrading of the plastic manufacturing industry. From core components of industrial equipment to daily-use plastic products, the in-depth integration of these three elements not only addresses the pain point of traditional manufacturing—"sufficient standardization but insufficient flexibility"—but also spawns an entirely new production model. In this field,
BOST is a professional plastic manufacturer specializing in custom plastic injection molding, which consistently uses technological innovation as a link to seamlessly integrate the three, providing efficient solutions for various industries.
Machined parts are not an independent link; instead, they serve as a key support for realizing the functionality and precision of plastic products after injection molding. Compared with metal machining, plastic part machining places greater emphasis on "flexible adaptation"—it must not only avoid deformation caused by material properties during processing but also ensure that dimensional tolerances are controlled within the micron range.
The current mainstream machining methods for plastic parts mainly include CNC milling, drilling, and polishing. In the 3C industry, injection-molded mobile phone camera brackets require five-axis CNC milling for their mounting surfaces to ensure that the fit error with the lens module does not exceed 0.01mm. In the medical field, the push rods of plastic syringes need precision polishing to remove surface burrs, preventing scratches to human tissues during use. Additionally, for plastic parts with complex structures (such as automotive sensor housings), laser engraving technology is introduced in the machining process to achieve accurate marking of QR code traceability labels.
BOST boasts a mature process system in the machined parts segment. Its high-speed CNC machining centers can operate continuously for 24 hours, and when combined with its independently developed fixture positioning system, the pass rate of plastic part machining can be stably maintained above 99.5%, perfectly connecting the upstream injection molding and downstream assembly processes.
The injection molding process is the core technology for the large-scale production of plastic products. Through a closed-loop process of "material melting—high-pressure injection—mold shaping—cooling and demolding," it transforms plastic pellets into products of various shapes, and boasts three major advantages: "high efficiency, energy saving, and integration."
In terms of material adaptability, the injection molding process is compatible with nearly 100 types of thermoplastic materials, such as ABS, PP, PC, and PA66. By adding reinforcing materials like glass fiber or carbon fiber, it can also enhance the strength and temperature resistance of products. In the automotive industry, injection-molded engine intake manifolds made of PA66 + 30% glass fiber can withstand temperatures of 120°C and are 40% lighter than metal parts. In the home appliance sector, injection-molded washing machine inner tubs made of PP material have become the industry standard due to their excellent corrosion resistance and low cost.
Process optimization is the core competitiveness of injection molding. BOST is a professional plastic manufacturer specializing in custom plastic injection molding. By introducing an AI temperature control system, it can adjust the barrel temperature, injection pressure, and holding time of injection molding machines in real time. For thin-walled plastic parts (such as laptop keyboard brackets with a thickness of 0.8mm), it can effectively avoid defects like material shortage and flash, increasing production efficiency by more than 30%.
As market demand shifts from "mass homogeneity" to "small-batch and multi-variety," custom plastic injection molding has gradually become the industry mainstream. Its core value lies in "design on demand and flexible production"—it can provide full-process customized services from mold development to finished product delivery based on customers’ product functions, application scenarios, and production volume requirements.
In the new energy sector, an energy storage equipment enterprise needed custom-shaped plastic junction boxes, which required an IP67 waterproof rating and compatibility with cable interfaces of different specifications. BOST used 3D printing to quickly produce mold prototypes, completing sample verification in just 5 days. It then optimized the mold structure based on customer feedback, and finally achieved small-batch custom production of 100 units per batch, with the delivery cycle controlled within 10 days. In the medical field, for the custom plastic handles of a rehabilitation device, BOST used medical-grade PE material, integrated anti-slip textures and ergonomic grip curves through a customized injection molding process, meeting the strict standards for medical products.
BOST is a professional plastic manufacturer specializing in custom plastic injection molding. Its customized services cover five key links: "demand analysis—mold design—process debugging—finished product machining—quality inspection." It can undertake orders ranging from 10 samples to 100,000 mass-produced units, and is particularly adept at solving customization challenges involving complex structures and special materials, helping customers shorten their product launch cycles.
Machined parts, injection molding process, and custom plastic injection molding do not exist in isolation; instead, they form a synergistic relationship where "customized demand drives the injection molding process, and injection molding supports machining precision." Take the smart watch case in the consumer electronics industry as an example: first, the size, color, and button structure of the case are determined based on customer customization needs; then, through the injection molding process, PC/PMMA composite materials are used to achieve integrated molding of the transparent bezel and colored case body; finally, CNC milling is applied to machine the case edges and button grooves to ensure precise assembly with the watch strap. This entire process can be seamlessly connected in BOST’s production line, saving 50% of the time cost compared with the traditional segmented production model.
This synergistic model also plays an important role in the industrial automation field. An automation equipment manufacturer needed custom plastic transmission gears. BOST first used the custom injection molding process and reinforced PA material to ensure the gear strength; then, in the precision machined parts segment, it performed honing on the gear tooth surfaces to reduce transmission noise. The service life of the final product is more than twice that of standard parts.
With the popularization of intelligent manufacturing technology, machined parts, injection molding process, and custom plastic injection molding will further upgrade toward "intelligence and green development." BOST has begun to deploy digital twin technology; by building a virtual simulation system for injection molding production, it can predict deviations in process parameters in advance and reduce the number of mold trials. In the machined parts segment, it has introduced visual inspection equipment to realize automatic detection of dimensional accuracy and reduce labor costs. At the same time, BOST is also promoting the use of degradable PLA materials in custom plastic injection molding, and combining them with energy-saving injection molding equipment to reduce carbon emissions during production and help customers achieve green production goals.
From precision control to personalized customization, from efficiency improvement to green transformation, the integrated innovation of machined parts, injection molding process, and custom plastic injection molding is driving the plastic manufacturing industry toward a higher-quality development stage. As a professional manufacturer specializing in custom plastic injection molding, BOST will continue to focus on technology as its core, providing more efficient, flexible, and environmentally friendly plastic manufacturing solutions for customers in various industries.
