FAQs
Q1: What is the average life of a tooling for an LSR injection mold, and how does JS Precision ensure it?
Well, the life of an LSR injection mold depends heavily on the choice of mold steel. Typically, for mass-production molds, imported S136 or 420ESR stainless steel of hardness HRC 52-54 is used. With conventional maintenance, mold life can easily and reliably extend beyond 1 million cycles. We offer mass-production customers free maintenance and even a lifetime replacement warranty for their core parts.
Q2: How does JS Precision reduce tooling costs for LSR injection molding by more than 35% over Western competitors?
First of all, we take advantage of Dongguan's well-established industrial cluster and one-stop closed-loop production to totally cut outsourcing expenses. Then, mix efficient local engineering and time bonuses, at the same time keeping a precise tolerance level of ±0.005mm, and our LSR injection molding molds overall cost can be lowered by 35%-45%. This is a great offer compared to foreign manufacturers by a wide margin.
Q3: What major changes in mold design are required when switching from high consistency rubber (HCR) to liquid silicone rubber (LSR)?
Most HCR rubber is compression molded, which produces large molding gaps and has the tendency to create thick flash. LSR is a liquid at low temperature, so it relies on high-pressure precision injection molding. It also needs a water-cooled runner, a parting gap of 0.005mm precision, and a mold cavity vacuum system to eliminate shortage and overflow defects of the material.
Q4: How do you handle the extreme temperature gradient that occurs in two-shot overmolding while producing automotive LSR parts?
This temperature difference issue in two-shot overmolding is tackled by using a independently temperature-controlled mold structure. Between the hard plastic cavity and the LSR molding cavity, a PEEK heat-insulating gasket is placed to keep a temperature difference of 80℃ quite stable. In this way, the plastic part at a high temperature won't deform, and the LSR will have enough time for cross-linking and can be cured properly. So, the solution is suitable for automotive LSR parts.
Q5: How does JS Precision determine and fix filling imbalance for the molding of multi-cavity medical sealing components?
The biggest reason of flow imbalance in multi-cavity molding of medical sealing components is the shear-thinning property of LSR. Our team manages to keep the shear rate variation of each cavity within ±3% by adjusting the needle valve stroke and flow channel cross-section, and also performing CAE fluid simulation. This way, the filling pressure is equalized and flash and short-fill defects are completely removed.
Q6: Will JS Precision take low MOQ or rapid prototyping orders for custom silicone seals?
We basically have no minimum order quantity (MOQ) conditions. This way, we completely adjust to the small-batch iteration needs of the R&D phase. We can very quickly make simple aluminum or P20 prototype molds, and you will get test samples in 7-10 business days. To customize rapid prototyping solutions efficiently and verify product structure and sealing performance, you can directly upload drawings.
Q7: What kinds of cleanroom and quality assurance methods does JS Precision use for medical LSR toolings?
We use an ISO 8 cleanroom for the entire medical-grade LSR mold production, ensuring a closed-loop and sterilized environment from raw material proportioning, injection molding, robotic part handling, to aseptic packaging. With 100% CCD inspection and FDA-certified raw materials, a full set of statutory test reports can be issued to meet medical access standards.
Q8: What kind of information is needed to get a detailed quote for your LSR injection mold tooling service?
You should send 3D/2D engineering drawings, type of raw material or hardness parameters, and approximate mass production capacity so that you get the quote that represents your LSR injection mold job as closely as possible. Afterwards, we are able to do cost estimation within 4-8 hours, and we even give you a formal standardized all-English quotation and project proposal.
Summary
Zero-defect mass production of medical and automotive LSR seals depend upon ±0.003mm mold precision, precision vacuum degassing, a needle valve cold runner balancing system and a compliant production system. It takes rigidity of mold steel, micron level structural design, non-linear shrinkage compensation to achieve no flash, no porosity and no failure of the seals. It is also the nature to accelerate product time-to-market and projects ROI.
If you have encountered something like seal molding failure, or dimension out of tolerance, and low mass production yield, (etc.), there is no need to repeat trial squeezing, and then loss costs. Please submit project parameters and drawings, and learn our professional engineer make customization DFM report and cost down quotation for you, that enable your company zero-defect mass production and grasp the market chance.
