  4.Diversified material properties

  Thermoplastic plastics cover a wide range of types from general purpose plastics to high performance plastics such as:

  • ABS: Resilience combined with surface gloss, suitable for home appliance housing.
  • PA (nylon): high abrasion and tensile strength for gears and bearings.
  • PC: High temperature resistant, transparent, for bulletproof glass or lighting fixtures.

  This diversity enables plastic molding to adapt flexibly to the functional requirements of different products and further improve performance through modification techniques.

  5.Environmental compatibility

  The recyclability of thermoplastic materials is in line with global environmental trends and reduces the environmental impact of injection molding production production chains. For example, replacing raw materials with recycled plastics (such as rPET) would not only reduce carbon emissions, but would also meet limits on harmful substances imposed by EU regulations such as RoHS. In addition, some thermoplastic materials,such as PLA polylactic acid, are biodegradable and suitable for single-use medical supplies or food packaging, reducing white pollution.

  

  What is the core basis for selecting injection molding materials? ​

  1.Product functional requirements drive material selection

  Application scenarios: Temperature resistance (e.g. engine components requiring 200 °C heat resistance), bearing capacity (e.g. mechanical parts), sealing performance (e.g. medical catheters), etc.

  Functional requirements: Electrical conductivity (electronic components), antimicrobial properties (everyday products), transparency (lighting fixtures), etc.

  JS technology:

  • Simulation system: Optimize gate design by analyzing the shrinkage rate and warpage deformation of the material by means of modulus flow (35% reduction in warpage rate of an automotive component).

  3.Compatibility guarantee of processing technologies

  Fluidity: Thin-walled parts require high plastic fluidity (e.g. ABS) and thick-walled parts can be selected for low viscosity PP.

  Shrinkage control: Precision parts (such as phone frames) require low shrinkage materials (such as POM).

  Mold lifespan: Corrosive materials such as PVC require chrome molds, while silicone injection molding requires a high temperature resistant coating.

  JS technology:

  • Thermal flow channel system: Multi-cavity die heat flow channel with tolerance of ±0.02mm supports 96-cavity injection molding.
  • Silicone secondary injection molding: Develop flexible cooling water channels and multi-stage vulcanization process for seamless integration of soft and hard rubber (silicone+plastic) such as handle grip.

  4.Balance between costs and mass production efficiency

  Material costs: The price difference between virgin and recycled plastics.

  Waste rate: Scrap recycling rate (95% by granulation technology).

  Production cycle: Rapid prototyping requirements (such as daily orders requiring 72 hours of delivery).

  JS technology:

  • Cost optimization solution: 30% fiberglass enhanced PA6 is recommended instead of pure PA6, reducing costs by 25% while maintaining strength.
  • Flexible production line: Supports small-scale pilot production (at least 100 units), mass production of millions of units per month, shortening a customer's production cycle by 60 days.

  5.Environmental compliance requirements

  Recyclability: Whether the material supports physical/chemical recycling (e.g. PCR recycling of plastics).

  Limit Hazardous Substances: Follow RoHS, REACH and other regulations (toys must be phthalate-free, for example).

  Biodegradability: Medical or packaging materials shall conform to EN 13432.

  JS technology association:

  • Environmental material certification: Provides FDA food grade, UL flame retardant certification and other reports to ensure product compliance.
  • Recycled plastics: An electronics brand has achieved 92% material recycling rate and zero landfill target through JS solution.

  What defects can occur when the temperature of silicone injection molding is too high? ​

  1.Pyrolysis of materials and residual volatile compounds

  • Defect manifestation: Too high a temperature can cause strands of silicone molecules to break, releasing low-molecular substances (such as acidic byproducts), form bubbles, silver lines on the surface or corroding molds.
  • JS adopts a special temperature control system for silicone molding to monitor and regulate screw temperature (accuracy ±1℃) in real time to avoid local overheating.

  2.Uneven color and yellowing phenomenon

  • Defect manifestation: High temperature will accelerate the oxidation of pigments or additives, resulting in product color difference or overall yellowing, affecting the consistency of appearance.
  • Precision color masterbatch measuring device is embedded in injection molding to ensure uniform dispersion of chromophore at high temperature.

  3.Uncontrolled size shrinkage and deformation

  • Defect manifestation: Excessive vulcanization leads to abnormal cross-linking density silicone gel, shrinkage rate deviates from the design value, causing product warping or assembly failure.
  • Dynamic feedback of mold sensors vulcanization degree, optimization of silicone molding process parameters, so as to shorten the cooling time by 20%.

  4.Mechanical deterioration

  • Defect manifestation: high temperature will destroy the molecular structure of silicone gel, resulting in a decrease in tensile strength and tear strength, affecting the durability of the product.
  • JS has developed high-strength silicone composites,such as fiberglass reinforced ones, that increased the tensile strength of industrial sealing ring engineering by 30%.

  5.Mold thermal damage and shorter service life

  • Defect manifestation: High temperature will accelerate the oxidation of mold steel, clog or deform the nozzle of the heat channel, increase the frequency and cost of maintenance.
  • JS technology association: The die has a DLC diamond coating (HRC 60+), a high temperature and corrosion resistant heat flow system with independent temperature field control (± 0.5℃ accuracy) to prevent overheating in the nozzle area and a 30% reduction in maintenance frequency.

  

  Summary

  In the field of injection molding, material selection is the core factor that determines product performance and cost. From basic plastic molding to high performance engineering plastics to special silicone molding, different materials meet the diverse needs of automotive, medical and electronics industries due to their high temperature resistance, strength, elasticity and environmental protection. With increasing environmental regulations, the application of biodegradable plastics (such as plastics) and recycled materials has become a trend, promoting green manufacturing practices.

  In this process, JS maximizes the potential of injection molding technology through precision die design, intelligent temperature control systems and modification technology. In the future, injection molding will continue to play a key role in lightweight, functionally integrated, and sustainable development as materials science and manufacturing technologies are deeply integrated.
