R&D capability
We recognize that your product designs, silicone formulations, and manufacturing processes represent significant R&D investment. Derui is committed to safeguarding your intellectual property at every stage of our partnership:
Mold design and engineering capabilitiesComplex mold development: Capable of designing cold runner molds, multi cavity molds, and encapsulated molds.
CAE mold flow analysis: Simulate the flow of silicone gel through software before mold opening, predict risks such as bubbles and missing glue, and optimize gate and exhaust design.
DFM feedback: Able to quickly provide manufacturability analysis reports upon receiving customer drawings, identify design hazards, and provide optimization suggestions.
Materials Science and Formula ApplicationMaterial selection support: Familiar with the characteristics of silicone with different hardness, viscosity, and tear strength, able to assist customers in selecting the most suitable grade for medical or maternal and child applications.
Dual/multi material bonding technology: proficient in handling the encapsulation process of LSR and plastics (such as PC, PA, PBT), solving problems of weak adhesion or overflow.
Compliance control: Familiar with medical/food grade standards such as FDA, LFGB, USP Class VI, etc., to ensure that the formula meets export requirements.
Rapid prototyping and prototype verificationRapid mold/soft mold development: Provide small batch trial mold services to enable customers to verify product structure and functionality before mass production.
3D Printing Assistance: Utilizing 3D printing to create inspection tools or appearance prototypes, shortening the initial confirmation time.
Process optimization and automationAutomated deburring: Developing solutions for frozen deburring or automated robotic picking to reduce manual contact and ensure product cleanliness.
Online inspection technology: Introducing a visual inspection system to automatically identify product defects and improve shipment yield.
Testing and Verification CapabilityInternal laboratory: It has the basic detection capabilities of dimension measurement (anime/third dimension), tensile test, hardness test, aging test, etc.
Simulate real environments: able to simulate the stress and temperature resistance of products in actual use, and detect potential failure modes in advance.
Customized solutionsAssembly and packaging research and development: Not only can we produce parts, but we can also develop automatic assembly lines and provide finished product delivery solutions.
Fixture and tooling design: Design specialized production fixtures for specific products to ensure consistency and stability in production.
