标准的注射机可用于生产多种薄壁制品。目前新型注射机的性能大大超过了 10 年以前。材料、浇口技术以及设计的进步，进一步拓宽了标准注射机对薄壁制件充模的性能。但由于壁厚不断减少，需要一种更特殊的、具有高速和高压性能的注射机。例如，一个厚度小于 1mm 的电子制件，充模时间小于 0.5 秒且注塑压力超过 210MPa 是很正常的。
The standard injection machine can be used to produce many kinds of thin-walled products. At present, the performance of the new injection machine is much better than that of 10 years ago. With the development of material, gate technology and design, the performance of standard injection machine for filling thin-walled parts is further expanded. However, due to the continuous reduction of wall thickness, a more special injection machine with high-speed and high-pressure performance is needed. For example, it is normal for an electronic part with thickness less than 1mm, filling time less than 0.5s and injection pressure more than 210mpa.
用于薄壁注塑的液压式注射机设计有储压器，可频繁地驱动注塑和合模。具有高速和高压性能的全电动注射机和电动/液压式注射机也面世了。为了能经受得住新型注射机的高压，锁模力的最小值必须是 5～7 吨/英寸（投影面积）。另外，当壁厚减少注塑压力增加时，大型模板有助于减少弯曲。薄壁制品用的注射机的拉杆对模板厚度的比为 2:1 或更低。生产薄壁制品时，注塑速度和压力以及其它加工参数的死循环控制有助于在高压和高速下控制充模和保压。
The hydraulic injection machine for thin-wall injection molding is designed with a pressure accumulator, which can drive injection molding and mold closing frequently. All electric injection machines and electric / hydraulic injection machines with high-speed and high-pressure performance are also available. In order to withstand the high pressure of the new injection machine, the minimum value of clamping force must be 5-7 tons / inch (projection area). In addition, when the wall thickness decreases and the injection pressure increases, the large formwork helps to reduce the bending. The ratio of the pull rod of the injection machine for thin-walled products to the thickness of the formwork is 2:1 or less. In the production of thin-walled products, the control of injection speed and pressure, as well as other processing parameters, is helpful to control the filling and pressure maintaining under high pressure and high speed.
至于注射量，大直径机筒往往太大了，建议的注射量为机筒容量的 40%～70%，薄壁制品总成型周期大大缩短，有可能将最小注射量减少到机粪池模具 路缘石模具 唐山通风管道 塑钢电缆挂钩 钢纤维 钢制拍门  筒容量的20%～30%。用户在注塑时必须十分小心，因为对材料来说，小的注射量意味着材料在机筒内的滞留时间更长，从而会导致制品性能的下降。
As for the injection volume, the large-diameter cylinder is often too large. The recommended injection volume is 40% - 70% of the cylinder capacity. The total molding cycle of thin-walled products is greatly shortened. It is possible to reduce the minimum injection volume to 20% - 30% of the cylinder capacity. Users must be very careful when injection molding, because for materials, a small injection volume means that the material stays in the barrel for a longer time, which will lead to the degradation of product performance.
