Why Choose Injection-Molded Prototypes?
In the early R&D stage, products typically rely on 3D printing, CNC machining, or Vacuum casting to produce prototypes for verifying appearance and structure. However, in the mid-to-late R&D phase, when conducting pre-mass production simulation tests on pre-selected material types, molding stability, structural strength, and other critical performance indicators of components, traditional prototyping methods such as 3D printing，CNC machining can no longer meet the requirements.
This is particularly true for precision internal structural parts used in automotive, aerospace, precision equipment, and other high-end industries. To mitigate design risks and reduce R&D costs, it is crucial to conduct comprehensive experimental verification on molding material selection, molding performance, component assembly, durability, strength, stability, and other key aspects before mass production.
We produce injection-molded prototypes under the same conditions as mass production—such as utilizing steel molds and the same plastic materials as those for mass production. Consequently, the precision of our molded prototypes is nearly identical to that of regular injection-molded parts. This enables our clients to conduct tests for verifying the following items prior to mass production, ensuring the overall performance indicators and production stability:
1, Verification of plastic part design
2, Verification of mold design
3, Verification of resin flowability
4, Verification of the function and strength of plastic parts
5, Verification of the overall performance indicators of plastic parts
Applications of HPDI's Injection-Molded Prototype Molding Process
HPDI's injection-molded prototypes achieve the same precision as mass-produced injection-molded parts, making them suitable for both R&D testing purposes and small-batch injection production.
Based on application scenarios, HPDI's prototype injection molding processes are divided into two types: prototype injection molds (also known as test molds) and bridge mold for small-batch production (also known as rapid tooling or rapid molds).
1. Prototype Injection Moulds
Applied for inspection and verification of various indicators during the component R&D phase.
Performance Testing & Verification of Injection Materials
Trial molds can be used to conduct injection molding tests on different materials, evaluating and verifying material molding efficiency, stability, and the structural strength of injection-molded parts. This provides a reliable basis for material selection during official mass production.
Structural Design Inspection
(e.g., strength, mold opening cost, and injection molding stability inspection)
Since injection-molded prototypes produced by HPDI's simple molds meet mass production-level precision and adopt identical processing conditions as mass production, they enable comprehensive verification of design feasibility. This includes inspecting the rationality of structural design, mold release smoothness, and mold opening costs. Additionally, injection tests with simple molds can identify potential issues that may arise during mass production, allowing for the development of preventive plans and providing data support for design optimization.
2. Bridge Molds for Small-Batch Injection Production
HPDI's bridge molds are characterized by low cost, mass production-level precision, and fast delivery. Compared with standard mass production molds, they can reduce costs by approximately 40%-50% and shorten mold manufacturing time by 50-60%.Therefore, HPDI's Bridge molds are a more cost-effective choice for projects requiring a small number of parts or for pre-mass production small-batch trial sales. They not only save R&D time but also reduce development costs significantly.

With short production cycles, cost-effectiveness, and high precision, HPDI's prototype injection molds effectively meet customers’ needs for R&D testing and low-volume trial production, earning long-term trust and high recognition from clients worldwide. HPDI has become an authorized supplier for several renowned international automotive and equipment manufacturers from Japan and Germany.
The machining precision of HPDI’s injection-molded prototypes is fully comparable to that of mass-produced injection-molded parts. Both the materials and processes adopted for the prototypes are identical to those of mass-produced parts, enabling comprehensive performance verification, testing, simulation, and evaluation of R&D projects. Meanwhile, the service life of Huawei’s prototype injection molds for injection molding can exceed 50,000 shots, which is fully capable of supporting low-volume injection production.
Injection-molded parts produced by HPDI’s prototype injection molds (or rapid molds) are mainly used as precision structural components in automobiles, medical equipment, communications devices, machinery, and large-scale equipment. They serve for simulation testing and verification during the R&D and design phases, as well as pre-mass-production testing and validation.

Our Quality Control
“Quality products are manufactured, not merely inspected.” At HPDI, our manufacturing philosophy centers on preventive management. Quality control must start from the source: one inspection at the preceding process is better than ten inspections at the later stage. The earlier problems are identified, the less waste from defective rework, and the more effective we are at preventing troubles before they occur.
HPDI has established a complete quality control system and strict quality standards. Our QC personnel conduct part inspections in strict accordance with the operating standards specified in the Inspection Work Instructions across the following three stages, ensuring that all part specifications and dimensions fully meet the requirements of customers’ drawings.
Stage 1: At the start of processing
Stage 2: During processing
Stage 3: Prior to shipment
Applications:
Our Prototype injection molds, bridge molds, rapid molds, injection molded prototypes or mold parts are mainly used for simulation testing, verification and small-batch injection molding production in the R&D and design phase of precision structural parts for automotive, aerospace, communications, medical and other industries.
